Correct tablespace names are now shown in the list of tables.

Slightly more complex then you may expect because the tablespace specified by the tables tends to be oid 0
which means the default tablespace is used. However this does not mean pg_default, it means the tablespace
as defined as standard in the database definition. So we need to know what the current dbname is retrieve
it's details from the catalog and retrieve that tablespace to know what to show for an oid of 0.
