+    The PostgreSQL source performs parallel snapshotting of tables by distributing rows among
+    workers using ranges of
+    [`CTID`](https://www.postgresql.org/docs/current/ddl-system-columns.html#DDL-SYSTEM-COLUMNS-CTID).
+    Materialize uses
+    [PostgreSQL statistics to estimate](https://www.postgresql.org/docs/current/row-estimation-examples.html)
+    the amount of data and number of rows to read. Missing or stale statistics can result in uneven
+    work distribution, reducing snapshot performance. They can also cause incorrect snapshot
+    progress reporting in the Console.
+
+    To avoid this situation, before creating the source in Materialize, ensure statistics are up to
+    date by running PostgreSQL `ANALYZE` command.
