Hmm, this is where I'm getting the oid's:

DATABASE -- pg_database
INDEX -- pg_class
RULE -- pg_rewrite
SEQUENCE -- pg_class
TABLE -- pg_class
TYPE -- pg_type
VIEW -- pg_class
COLUMN -- pg_attribute
AGGREGATE -- pg_aggregate
FUNCTION -- pg_proc
OPERATOR -- pg_operator
TRIGGER -- pg_trigger

So in the example you gave above, you could put a comment
on each of the two functions which compose the operator
and a command on the operator itself.

I still need to write the SGML and change pg_dump to
generate COMMENT ON statements, and also regression tests,
but the functionality should be complete. Just glancing
over the Win32 ODBC driver, it appears that SQLTables() and
SQLColumns() is not currently fetching the associated
description from pg_description for the REMARKS parameter
to the call. Perhaps this could be changed? 

Hope that helps, 

Mike Mascari (looking forward to the new psql...)
