It means that additional databases will be built for SLE/openSUSE 15 and newer,
but also for Leap newer than 42.1. But this has nothing to do with the problem
at hand.

I've added "BuildRequires: postgresql-server-devel" to minetest as a temporary
workaround, because the actual fix has to be done in CMake which doesn't
distinguish between client applications and server extensions when being asked
for PostgreSQL.

Here is the respective upstream bug:

And here is my submit request with the workaround:
