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.

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.
