Re: Upgrading side by side in Gentoo

Where to get ready binaries which can be copied and ran in Gentoo ? Is
there any how-to pages or tips about compiling PostgreSql from source in
this Gentoo ?

This would do more harm than good so *don't*.

How can compiling PostgreSql 8.3.x from source on Gentoo do more harm than good ? I expect that compiling form source operates on different environment which will not touch existing
working 8.1.4 server
Only shared resource is listening port (5432) and I can set it to some other for testing.

No matter what you do you will have to dump the DB to upgrade it from
8.1.x anyway so some downtime is unavoidable. Depending on the contents
you may even have to fix some bits of the schema since 8.3 is more strict
than 8.1 in some ways. This is the hard part, and it has *nothing* to do
with Gentoo; upgrading your installation is the easiest part and will only
take a few minutes since it is completely automated (2 or 3 commands).

Last shop will closed at 24:00 and first is opened at 6:30 am.
So there is 6.5 hours allowed downtime in every night in this server.
Client applicaton which uses this server and db schema works with lot of 8.2 and 8.3 servers.
So I expect that server version change will be transparent to users.

Andrus.
