Fixups for a4f774cf1c

The database name was warned about when building with
-DENFORCE_REGRESSION_TEST_NAME_RESTRICTIONS, leading to BF and CI failures.

It is somewhat confusing that the required prefix is different for databases
than other object types.

Also fix a pgindent violation that caused koel to start to fail.
