The following documentation comment has been logged on the website: Page: https://www.postgresql.org/docs/17/docguide.html Description:
Hello there, I like PostgreSQL a lot so this is my way of giving back. The "table scan is skipped" optimization can use some clarification https://www.postgresql.org/docs/current/sql-altertable.html#SQL-ALTERTABLE-DESC-SET-DROP-NOT-NULL My proposal is "then the table scan is skipped if the alter statement doesn't drop the constraint." The reason behind the proposal is documented here https://dev.to/andrewpsy/the-set-not-null-downtime-trap-in-postgresql-1o71 Thank you for working on such an awesome project. Cheers, Andrew
