OK. I'll see what can be done with the docs. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers

I'm not sure, how to incorporate this into current documentation, since there is no built-in filtering dictionary. Probably, it'd be nice to add filtering option to simple dictionary to illustrate this feature.
