Hi group! I've seen the page http://www.postgresql.org/idocs/index.php?routine-vacuuming.html where is explained the benefit offered by the vaccum.
I've made a test with my software: before vaccuming: 478 "operations" after vaccuming: 1378 "operations" Good, but the documentation reports: - Beginning in PostgreSQL 7.2, the standard form of VACUUM can run in parallel with normal database operations. If my DB is a 7.1.3 what happens? - Prior to PostgreSQL 7.2, the only defense against XID wraparound was to re-initdb at least every 4 billion transactions. And in the 7.1.3 Is it safe to run the vaccum on a production DB? I've also planned to setup a ramdisk to improve the performances.. is it a good choice? TIA, Auri ---------------------------(end of broadcast)--------------------------- TIP 4: Don't 'kill -9' the postmaster
