Current status

• Targeted release: Fedora 33

• FESCo issue: #2448
• Tracker bug: <will be assigned by the Wrangler>

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:
  • 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
  • Rebuild those packages against PostgreSQL/Libpq 13 (see Dependencies)
  • Gather user input on the changes between PostgreSQL 12 and PostgreSQL 13

• Other developers: N/A (not a System Wide Change)

• Release engineering: #Releng issue number (a check of an impact with Release Engineering is needed)

• Policies and guidelines: N/A (not a System Wide Change)

• Trademark approval: N/A (not needed for this Change)

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 versions.

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.
