Subject: [PATCH] Support compilation and run tests on latest PG versions
 (#6711)

Postgres got minor updates this starts using the images with the latest
version for our tests.

These new Postgres versions caused a compilation issue in PG14 and PG13
due to some function being backported that we had already backported
ourselves. Due this backport being a static inline function it doesn't
matter who provides this and there will be no linkage errors when either
running old Citus packages on new PG versions or the other way around.

(cherry picked from commit 3200187757600180fa2b90a5fdba13cbf8aee8b6)
