Hi, One of our PostgreSQL databases is generating archive logs too frequently, since the number of transactions/s (inserts & updates) is very high.
I was looking for a parameter on postgresql.conf to increase the WAL segments size, but according to documentation this can only be changed while building PostgreSQL. Some questions came up to my mind when I read that: 1. For databases with this kind of behavior (high number of inserts & updates), wouldn't be better (from the performance point of view) to have larger WAL segments? 2. Is there a special reason to not allow the WAL size to be changed on postgresql.conf (version 8.2 or 8.3)? Best regards, Bruno Lago ---------------------------(end of broadcast)--------------------------- TIP 2: Don't 'kill -9' the postmaster
