Is it correct that calling attrelid::regclass will always return a
non-schema qualified relation name
ie:
WHERE there is a temp table and a permanent table of the the same name
SELECT attrelid::regclass
FROM pg_attribute
WHERE attrelid = 'tagdata'::regclass
will always use the "current" temp table of the name or the permanent
table if no temp table exists without schema qualification.
So this would be the same as a normal select , ie:uses temp table/permanent
table as appropriate
