Volker mentioned an install with a dependency "postgres" fails if
postgresql is installed with -DWITHOUT_SERVER, though it shouldn't,
and thus suggested a depend-change to "psql", which is also present
for the client-only-install.
The maintainer then submitted the patch which completely removes the
dependency as it "is actually not needed". I personally am in favor
of the first solution, but Palle is the maintainer.
