+A：在物理机上在 /etc/sysctl.conf 中配置 vm.overcommit_memory=2（以及一些其它参数）之后，不会发生数据库被 OOM 给 killed 掉的情况。这是，当内存不足时，执行的 SQL 会因为申请不到新内存而直接报错，符合用户的预期。而如果使用容器的内存限制，则无法达到这个效果。目前这个问题在容器中没有太好的解决办法。
A：IvorySQL 与 Patroni 完美适配，Patroni 作为支持 PG 的高可用工具，十分完备且社区活跃，可以通过 Patroni 进行 IvorySQL 高可用集群搭建。
+A：完全可以将 IvorySQL 作为 Oracle 数据库进行使用，与 Oracle 自身并无关联。
+A：database 模式决定了初始化时，初始化的是 Oracle 兼容的 PG 数据库还是原生的 PG 数据库，一旦初始化就无法进行修改。原生的 PG 数据库无法支持 Oracle 兼容特性。

+具体来说：Linux kerenl 版本< 5.1 原版 PostgreSQL 18 不能使用 `io_methods=io_uring`，Linux kernel<5.6 不建议使用 `io_method=io_uring`。
+由于 PostgreSQL 本身其实是与授权服务器是完全解耦的，所以资源消耗主要取决于授权服务器。
+对于授权服务器而言，从性能消耗的角度去看涉及到的工作主要有令牌的生成、接收网络请求、授权服务的维护工作如日志采集和归档等，这些会消耗一定的 CPU、内存资源。令牌的存储以及令牌与数据库用户之间的 MAP 映射关系的存储会消耗服务器的存储资源。总的来说 CPU 和内存的资源消耗取决于授权频率，也就是 PostgreSQL 用户的登录频率，存储资源的消耗取决于 PostgreSQL 的用户数量。
+从网络开销上来看，首先是前期令牌的获取上，PostgreSQL 18 需要向授权服务器进行多次 HTTP 请求，当网络延迟过高时，登录的时间就会受影响，同时用户也需要向授权服务器发送 HTTP 请求进行验证请求，所以还需要考虑到用户与授权服务器间的网络延迟。在令牌的验证过程中，外部验证器与 PostgreSQL 服务端在同一台服务器，二者之间是不会有网络通信的，但是如果采取的是在线验证令牌的方式，就需要考虑外部验证器也就是 PostgreSQL 部署的服务器与授权服务器之间的网络延迟。
+从优化性能的角度考虑，授权服务器应尽量与 PostgreSQL 在同一局域网下，并且外部验证器可以考虑本地验证的方式去减少网络开销。
+PostgreSQL 18 中带虚拟列的表是可以做逻辑复制，因为虚拟列的值是依赖于其它列，只要其它列做了逻辑复制，虚拟列在查询时通过计算就能获取该列的值。只是逻辑复制不能单独的指定虚拟列（因为虚拟列没做值存储），但是可以指定存储列。

+A: On a physical machine, after configuring vm.overcommit_memory=2 (and other parameters) in /etc/sysctl.conf, the database will not be killed by OOM. Instead, when memory is insufficient, the executing SQL will throw an error directly because it cannot allocate new memory, which meets user expectations. However, using container memory limits cannot achieve this effect. Currently, there is no good solution for this issue in containers.
A: IvorySQL is perfectly compatible with Patroni. As a high-availability tool supporting PG, Patroni is very comprehensive and has an active community. You can use Patroni to build an IvorySQL high-availability cluster.
+A: You can fully use IvorySQL as an Oracle database; it has no direct connection with Oracle itself.
+A: Database mode determines at initialization whether an Oracle-compatible PG database or a native PG database is initialized. Once initialized, it cannot be modified. A native PG database cannot support Oracle compatibility features.
+A: It supports vertical scaling of CPU and Memory for database pods, and users can adjust them at any time.

+ io_uring as the AIO underlying implementation on old Linux kernels.Specifically: For Linux kernel versions < 5.1, the original PostgreSQL 18 cannot use io_methods=io_uring; for Linux kernels < 5.6, it is not recommended to use io_method=io_uring.
Since PostgreSQL itself is completely decoupled from the authorization server, resource consumption primarily depends on the authorization server.
+For the authorization server, performance consumption involves tasks like token generation, handling network requests, and maintenance work such as log collection and archiving, which consume CPU and memory resources. The storage of tokens and the MAP relationship between database users and tokens will consume server storage resources. Overall, CPU and memory consumption depend on the authorization frequency (the login frequency of PostgreSQL users), while storage consumption depends on the number of PostgreSQL users.
+From a network overhead perspective, PostgreSQL 18 needs to make multiple HTTP requests to the authorization server for initial token acquisition. High network latency will affect login time. Additionally, users need to send HTTP requests to the authorization server for verification, so the network latency between the user and the authorization server must also be considered. During token verification, if an external validator and the PostgreSQL server are on the same machine, there is no network communication; however, if online token verification is used, the latency between the PostgreSQL server and the authorization server must be taken into account.
+To optimize performance, the authorization server should be placed in the same local network as PostgreSQL as much as possible, and local verification can be considered for external validators to reduce network overhead.
+In PostgreSQL 18, tables with virtual columns can actually undergo logical replication. Because the value of a virtual column depends on other columns, as long as those other columns are replicated, the virtual column value can be calculated during a query. Logical replication simply cannot specify a virtual column individually (since virtual columns do not store values), but it can specify stored columns.

+ Since the launch of version 1.0 in 2021, the IvorySQL project has continued to iterate and upgrade, keeping pace with the evolution of the PostgreSQL kernel. IvorySQL 5.0, released in November 2025, is based on the PG 18 kernel and significantly improves system performance through advanced features such as Asynchronous I/O and Skip Scan. This version adds 21 new compatibility features, supports one-click installation for mainstream architectures such as x86/ARM/MIPS/LoongArch, and is adapted to domestic operating systems like Kylin and UOS. It features comprehensive cloud-native support and online trial functions while strengthening Oracle compatibility to provide users with a convenient and efficient experience. Additionally, IvorySQL actively carries out global joint R&D, reaching cooperation with companies such as OnGres in Spain and Data Bene in France to promote project integration and ecosystem construction.

+ + Winning the "2025 Product Innovation Award" is both a recognition of IvorySQL's technical innovation by the industry and an incentive for open-source ecosystem co-construction. In the future, IvorySQL will continue to work with community developers, industry partners, and users to deepen the PostgreSQL technical field, improve product capabilities, and jointly build the community ecosystem. +
+Hope and Oreo from the IvorySQL development team jointly introduced the core overview of the project. Launched in December 2021, the project has consistently maintained a synchronization rhythm with new PostgreSQL versions. The session highlighted three core features: the AI subsystem, Oracle semantic compatibility, and cloud-native deployment capabilities. IvorySQL has released its latest stable version (IvorySQL 5.0), and the team plans to launch version 5.1 within a month. At the end of the presentation, the guests showcased new extensions and encoding features and announced the upcoming in-depth seminar featuring Cédric from Data Bene.
+Cédric, founder and CEO of Data Bene, shared core challenges of migrating from Oracle to PostgreSQL based on European market practices. He emphasized that for large, long-running Oracle databases, ensuring business continuity is the primary difficulty, requiring support from efficient and reliable migration tools. Data Bene's full-process solution enables precise data export and import across different database engines, providing critical support for smooth enterprise migrations. Subsequently, Cary and Grant further discussed the core value of "reducing code rewriting costs," emphasizing it as a key link in improving migration efficiency and controlling project risks.
+Matthew comprehensively deconstructed the full migration process from Oracle to PostgreSQL, focusing on IvorySQL 5.0's solutions for migration pain points. Through a live demonstration, he intuitively showed how IvorySQL's PL/iSQL engine, invisible columns, and case conversion models precisely solve common migration issues. Cary emphasized the community-driven nature of IvorySQL development in this segment, encouraging participants to vote on feature priorities to help align project iterations with actual needs. An interactive Q&A session was set at the end of the presentation, where participants who answered questions correctly received exclusive prizes.
+Cary shared the detailed SQL feature roadmap for IvorySQL over the coming year, covering core functions such as Global Index, triggers, nested tables, autonomous transactions, and synonyms. He noted that several planned features align highly with current community voting results for SQL category improvements, reflecting the project's responsiveness to community needs. Cary stressed the importance of community feedback and encouraged users with personalized feature requirements to submit proposals via GitHub. Grant confirmed that the full roadmap and voting results would be synchronized with all participants later.
+The team held a specialized discussion on IoT scenario adaptation and Package support. Notably, Package support became the most concerned demand among participants with a 33% support rate. Cary mentioned that Alvaro commented on tool selection, pointing out the performance loss and security risks of Pgpool-II, and suggested adapting and combining solutions from PgBouncer and Patroni. Meanwhile, Alvaro expressed interest in pushing some of IvorySQL's core features into the standard PostgreSQL ecosystem.
+This webinar specifically explored the feasibility of "contributing features to the PostgreSQL community from cross-compatible projects." Alvaro proposed a core principle: feature contributions must prioritize the overall interests of the PostgreSQL community. Grant added that there are plans to give back highly adaptable features like Global Index to the community, though some Oracle compatibility features might not be suitable for direct migration due to architectural differences between the two databases. Cary further interpreted the complexity and cycle of submitting patches to PostgreSQL, illustrating with an example where a related feature patch took over a year to complete community review and acceptance.
+This webinar received active responses from global developers, with 32 registered participants and 27 actual attendees. Participants covered multiple countries and regions, including Canada, the United States, France, Spain, India, China, and Germany, achieving efficient exchange of technical experience across borders.
+IvorySQL sincerely thanks all participants for their active involvement and enthusiastic interaction, as well as the guest speakers for their professional insights and shared experience. In the future, the IvorySQL community will continue to focus on technical innovation and ecosystem construction in the field of Oracle to PostgreSQL migration. Through more high-quality technical exchange activities, we aim to build industry communication bridges, help more enterprises break through database migration bottlenecks, achieve smooth transformation, and jointly promote the prosperity and development of the open-source database ecosystem with global community members.

+
+ A: Switching IvorySQL to Oracle compatibility mode primarily affects syntax, functions, and data type behavior, but it does not modify existing data: records that originally distinguished between '' and NULL in the database will remain as they are.
+A: IvorySQL 5.1 is now live. IvorySQL's core procedural language is PL/iSQL, which introduces Oracle-style Packages, stored procedures, functions, and nested sub-functions, supporting common data types. Current known limitations: Packages only support partial features and are still under continuous development. Alternative: Use custom functions for implementation.
+A: Yes, multiple levels of nesting are supported. To prevent infinite recursion and resource exhaustion, the nesting limit is set to 200 levels.
