I have a schema which has a number of attributes called "name_id":
metadata=# select n.nspname, r.relname from pg_class r, pg_namespace n, pg_attribute a where a.attname = 'name_id' and
r.oid= attrelid and n.oid = relnamespace;nspname | relname

Change 'name_id' to 'myColumnName' and you should get what you're
