Public bug reported:
plr DEP8 tests have been failing for a while now. There are 2 different
reasons leading to the failures. The first one being observed at the
moment is due to the new r-base-core in resolute, which leads to the
following error in all architectures:
243s ### PostgreSQL 18 installcheck ###
243s Creating new PostgreSQL cluster 18/regress ...
251s Package libR was not found in the pkg-config search path.
251s Perhaps you should add the directory containing `libR.pc'
251s to the PKG_CONFIG_PATH environment variable
251s Package 'libR', required by 'virtual:world', not found
Still, when running the DEP8 tests without the new R packages in
resolute-proposed we can observe the following error only reproducible
in s390x:

After several runs of the same tests, we can observe that the failure
happens in the first test, which takes about a minute to run. After
that, postgresql segfaults and restarts, which leads to intermittent
failures for the following tests. While this may be due to resources
issues in our infrastructure, this needs further investigation for that
specific architecture.
