Re: Upgrading from 7.2.1 to 8.x

You can have a look through all the release notes from 7.2.1 to current to
see what will be fixed, including any data eating insects. Check this page
http://www.postgresql.org/docs/7.4/static/release.html

Obviously you'll need to test everything, but you should be able to install
the new version, use pg_dumpall to dump your DB, and then restore it to the
new version. Any errors that come up will need to be investigated.

Question,

I have an ancient database that is running Postgresql 7.2.1 on AIX. Is it
safe to directly upgrade the database to 8.1? If not, what steps do I need
to take?

I have been pushing for 3 years to upgrade this database, and with some
upcoming projects, I am going to do another push with management to upgrade
this database.

Also, I know there are a ton of fixes/improvements from 7.2, but are there
any major data losing bugs in this version that I can use as added pressure
on management?

Thanks,

Chris
