psycopg is included in RHEL 8, but PGDG packages are up2date (2.7.5 vs
2.9.5) so they override OS packages. That is why things will break.

A solution would be creating our own psycopg2 (likely for Python 3.12)
package, update all PGDG packages that depend on psycopg2 to use that
package. That is not impossible (I have already psycopg2 built against
Python 3.11 on SLES 15), but I don't know how much work it will be and
its impact as that set of update should go to both RHEL 8, 9 and 10
(RHEL 10 already includes Python 3.12 by default)

I can go for this solution if it is *absolutely* required. We already
have custom packages to support PostGIS, so that is not a new topic for
me.
