Incorporate changes in postgresql-server-dev-* package contents

[hanefi]

Some of the new postgresql-server-dev* packages no longer have pgxs libs and pg_config binary, and we should update our docker images to be able to build on most recent PG versions

This issue occurs at PG 11.7, 10.12, and possibly some more versions.

Possible workarounds:

• install postgresql-client-* packages that now has the necessary files.
• use outdated libpq packages that still has the required files

Check that the following still works:

• [ ] Docker images that are used for packaging
• [ ] Community and Enterprise install scripts
• [ ] The dependencies of packages may need to include more postgresql packages. To ensure that the dependencies are valid, we may want to manually test install the packages to make sure everything is ok.
