Hi, I'm about to write a simple one-way replication script relying on xmin and would like to speed up things by putting an index on it. So I have a few questions: 1. Will something bad happen if I put index on xmin ? 2. Is it just a bad idea to do it that way ? (there will be no deletes, just mainly inserts and some updates) ------------ Hannu ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
