Re: Increasing RAM for more than 4 Gb. using postgresql

You can *not* go from any major release to another major release using
any kind of file backup. Please use pg_dump.

Additionally there are known issues dumping and restoring from 7.3 ->
7.4 if you use the default copy command. Use the pg_dump --inserts option.

I would still tar the directory just in case you *have* to fall back to
7.3 for some reason (Better safe than sorry )
