support for postgresql 16

[Melkij]

Hello

So far there are no incompatible changes, 1.4.8 works with postgresql 16dev without any changes.

However, I propose to prepare a new release 1.4.9 as usual, I will mention postgresql 16 support in the change notes to eliminate any ambiguity.

Question for discussion: it is necessary to change the list of supported old versions? ( #338 )

PS: at the same time I want to check if pg16 is already available for our tests

update-alternatives: error: alternative path /usr/share/postgresql/16/man/man1/postmaster.1.gz doesn't exist
dpkg: error processing package postgresql-16 (--configure):
installed postgresql-16 package post-installation script subprocess returned error exit status 2

The package is available, but its installation fails. I'll trigger the check few weeks later.

This is currently failing with an unrelated error in the package:

update-alternatives: error: alternative path /usr/share/postgresql/16/man/man1/postmaster.1.gz doesn't exist
dpkg: error processing package postgresql-16 (--configure):
 installed postgresql-16 package post-installation script subprocess returned error exit status 2

I would like to separate the update of support for PG 16 and the cut of a new release. These two do not necessarily have to go into a single PR.

[andreasscherbaum]

We are discussing that instead of releasing 1.4.9 we release 1.5.0 as compatibility release for PG 16.

@Melkij Can you please rebase this patch? Thanks!

[Melkij]

I removed unrelated changes and ran tests locally. For postgresql 16 we didn't need any additional changes. This time, the github tests also passed without surprises.

Greetings!

Any news in regards to this? 👀

@franciscoreinolds , pg_repack 1.4.8 works fine with postgresql 16. No code changes were required. Regarding the mention of pg16 support in the documentation and tests... I lost the track.

@andreasscherbaum , I remember that a new release was planned.

[franciscoreinolds]

Indeed, I meant more if there had been a discussion to release a new version with the content of this PR just to explicitly support PG 16 👌🏽

[andreasscherbaum]

Yes, there is a bugfix we want to get in, and then release a version which mentions 16.

[dvarrazzo]

The file doc/pg_repack.rst must be updated too to declare the next version pg16-compatible.
