I see what Hiroshi is saying now --- there was a reference to
pg_namespace (in WHERE but not in FROM) _and_ a reference to 'pn' as an
alias for pg_namespace (in WHERE and FROM).

The attached patch fixes this by creating a pn1 and pn2 alias for
pg_namespace in FROM.  It also improves some of the alias tags.  Applied
to ODBC CVS.  Can someone run some tests on these?
