Any plans for qual pushdown? Yeah, I have (hopefully) working FDW for PostgreSQL which is based on the one which has been proposed for 9.1, and updates done by Heikki. I've implemented: * SELECT clause omitting * WHERE clause pushdown (assuming remote has same functions/oprators) * private connection caching, and VIEW which shows active connections * switch simple SELECT and CURSOR based on estimated # of rows, and FDW options to control this behavior I'd like to submit this fdw in CF 2011-09 (ASAP) for discussion of itself and FDW API enhancement.

It's just weird to have something show up in the list view that doesn't appear in the detail view. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
