I'm pretty sure there's some stuff in this patch that's not right in detail, but I think this is an awfully exciting direction. I'd like to commit David Rowley's patch from the other thread first, and then deal with this one afterwards. The only thing I feel strongly needs to be changed in that patch is CFUNC -> COMBINEFUNC, for clarity. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
