pgsql: Fix temporary tablespaces for shared filesets

Fix temporary tablespaces for shared filesets

A likely copy/paste error in 98e8b480532 from  back in 2004 would
cause temp tablespace to be reset to InvalidOid if temp_tablespaces
was set to the same value as the primary tablespace in the database.
This would cause shared filesets (such as for parallel hash joins)
to ignore them, putting the temporary files in the default tablespace
instead of the configured one. The bug is in the old code, but it
appears to have been exposed only once we had shared filesets.
