from version 12 to version 13 in the non-modular (main) builds.

== Detailed Description ==
Update of PostgreSQL (`postgresql` and `libpq` components) in Fedora
from version 12 to version 13 in the non-modular (main) builds.

This also involves updating and rebuilding the PostgreSQL plugins that
depend on postgresql server.

== Benefit to Fedora ==

Latest stable software is used by Fedora users.

== Scope ==
* Proposal owners:
<!-- What work do the feature owners have to accomplish to complete
the feature in time for release?  Is it a large change affecting many
parts of the distribution or is it a very isolated change? What are
those changes?-->
**Prepare PostgreSQL 13 as a module for Rawhide and at least one
stable Fedora release (done)
**Prepare PostgreSQL 12 as a module for Rawhide, so there would be a
failover in case of problems
**Build PostgreSQL 13 to Rawhide
**Check software that requires or depends on `postgresql-server` or
`libpq` packages for incompatibilities
**Gather user input on the changes between PostgreSQL 12 and PostgreSQL 13

== Upgrade/compatibility impact ==
The PostgreSQL client library (libpq component) is compatible, so
there shouldn't be any issues, but rebuild of the depended components
is better to be sure. There is a
COPR build] available for testing.
Server plugins might require a newer version update, because they
sometimes have explicit server requirements. PostgreSQL maintainer
will help fixing/rebuilding any issues in the plugins.

== How To Test ==

Usual testing as when upgrading between major PostgreSQL versions,
running `postgresql-setup --upgrade` is necessary between major

Test that all other software runs well with PostgreSQL 13.

== User Experience ==

The users will have to upgrade their databases the same way as between
major PostgreSQL versions, aka `postgresql-setup --upgrade`.

If users want to stick with PostgreSQL 12 for a little longer, there
should be PostgreSQL 12 module.
If users want to test it before it reaches Fedora 33, there is a
COPR build] available.

== Dependencies ==

There are some packages (mostly server plugins), that build on top of
PostgreSQL. Since the separation of PostgreSQL client library (libpq
component), only packages that build server plugins should use
postgresql package in BuildRequires, others should use libpq. In both
the cases, rebuild should be done to make sure all potential binary
incompatibilities are handled.

== Contingency Plan ==

Modules will provide the functional version of PostgreSQL 12,
available to all users.
