Support for all old EOL'd PG versions and solving all racing conditions? about pg_repack

[dvarrazzo]

No problem in stopping support for Postgres < 10 or 11.

As per the race conditions problem, they are difficult reproduce and to test. As far as I understand, it is a problem that the core team doesn't feel to solve either, which is the reason why this project has never really been considered to be included in core.

Well, I don't remove old versions if pg_repack passes tests without any changes. I don't have a plan to support certain versions. As long as they don't interfere, I leave it as is.

Why do you think VACUUM FULL has no enhancement path to add the CONCURRENTLY option?

I know: because no one is working on it. It's a long process to bring the discussion to a consensus, implement the patch and bring it to merge to the mainline. A lot of patches are stopped due to lack of attention during review.

I agree, as long as old versions are working, pg_repack can - and should - be tested on them.
Only if problems arise with old versions then they can be made EOL, and the documentation should be updated to reflect this.

Nice feedback, stuff to think about...
