Hi there!

Patch itself posted to pgsql-patches.

This is a new version of patch i've posted.
This for PG version 7.3rc1.

Changed syntax, now it's more closer to Oracle's and allows operator other
than '='.
Removed Const/Var trick, now it's a new FakeVar node used, as a side effect
it's not need initdb now.
Added little regression test.
Added more comments on code.
A bit extended README.hier .

working on SQL99 version.
