Bug reference:      18578
Logged by:          Costas Gargerakis
Email address:      cogarg@gmail.com
PostgreSQL version: 12.20
Operating system:   Rocky Linux 8
Description:

The postgresql12-devel-12.20-1PGDG.rhel8 rpm requires
'perl(PostgreSQL::Test::Utils)' and nothing else in the repository provides
it.
The older postgresql12-devel-12.19-3PGDG.rhel8.x86_64 does provide it.

While using rpmbuild/mock:
Error: 
 Problem: cannot install the best candidate for the job
  - nothing provides perl(PostgreSQL::Test::Utils) needed by
postgresql12-devel-12.20-1PGDG.rhel8.x86_64 from pgdg12
