Hi, If the downtime is a concern, you could use Slony-1 for the migration. Philippe Ferreira.

Upgrade from what to what? If you're upgrading from 8.0.x to 8.0.y then there is no dump/reload. If youre going from 8.1 to 8.1 then there is dump/reload OR you can use some sort of replication such as slony to copy the data, then have a few seconds of downtime while you turn off the older DB and put the 8.1 in its place. ---(end of broadcast)--- TIP 2: Don't 'kill -9' the postmaster

You want to make your dump with the pg_dump of the new version. I'm not sure you can build the tools seperately (that'd be excellent, but my FreeBSD boxes are at home)... I think it should be: 1 - make postgresql, 2 - make install postgresql-tools 3 - dump 4 - stop db 5 - make install postgresql 6 - restore 7 - start db -- Alban Hertroys [EMAIL PROTECTED] magproductions b.v.
