OK, how about on \d+, if the object is not on pg_default or pg_global, print
the tablespace that this object is on? That way, people not using tablespaces
won't ever see it.

OK, not fussed which one it's on, so long as it's there - this should do it
for \l+
SELECT d.datname as "Name", r.rolname as "Owner", pg_catalog.pg_encoding_to_char(d.encoding) as "Encoding",
pg_catalog.obj_description(d.oid,'pg_database') as "Description", t.spcname as "Tablespace"
FROM pg_catalog.pg_database d LEFT JOIN pg_catalog.pg_roles r ON d.datdba = r.oid LEFT JOIN
pg_catalog.pg_tablespacet on d.dattablespace = t.oid;
On a related note: is there a simple way to show all objects on a given
tablespace? If not, would other people also see this as useful?
Regards, Philip.
