Backup and restore from 7.4.1 to latest, crossing platforms... issues?

[Mark Mikulec <mikulec@xxxxxxxxx>]

Hi there,

This may be a stupid question but I feel I should ask it anyway just to be sure, since I've had problems in the past.

I currently have a defunct Debian 3.0 system running PostgreSQL 7.4.1, in
which I am going to do an entire blob backup dump of all the databases
in hopes to restore them on my new, more secure system running the
latest OpenBSD, and PgSQL 8.0.

So my question is: Are they any issues that I should be aware up
restoring on a more recent version of PgSQL, and/or issues using a
completely different operating system altogether? I have some strange
pg language mishaps going from 7.2 to 7.4 last backup, although
frightening, I overcame them with some fiddling.

Thanks in advance,
    Mark
