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
