Hmm, don't you find strange that dbcommands.h is still included there?
I wondered about that and found out that we have get_database_name()
declared there. It sort-of makes sense, because it was originally done
by scanning pg_database, but since commit cb98e6fb8fd4 introduced a
syscache for it, we can have this routine in lsyscache.c/h instead,
where it feels more at home. It also seems more sensible to declare
get_database_oid() in pg_database.h. After these two changes, a lot of
files can stop including dbcommands.h. This seems a nice cleanup to me,
and passes headerscheck.
