If we are paying for setting up a cluster we might as well test more scenarios
than just the one. Perhaps some other low-hanging fruit like calling vacuumlo
on a non-existing databsase, on one where no LO have been made etc?

One thing about the patch:

+IPC::Run::run [ 'vacuumlo', '-v', '-n', '-p', $port, 'postgres' ], '>', \$stdout;

This should use run_command() which provides facilities for running commands
and capturing STDOUT. With this the test can be rewritten something like:

my ($out, $err) = run_command(['vacuumlo', .. ]);
like($out, ..);

run_command() is defined in PostgreSQL::Test::Utils.
