Re: Load DB - Conversion from 8.1.4 to 8.2.4

I was thinking about upgrading from 8.1.4 to 8.1.9. Then I will do the
upgrade from 8.1.9 to 8.2.4.

Is this a better approach?

Thanks,

Two quick addendums:

- pg_dump doesn't dump large objects. You should use the following if
you use large objects.

pg_dump -h /host1/ -p 1234 -Fc /dbname/ | pg_restore -h /host1 -p 56789/

/dbname///

- There might be some other issues with the upgrade. I've run into
permissions issues, data types that were checked more strictly, and a
couple broken primary keys in my days as an admin. I'm not saying you'll

run into these, but if you can, do a dry run of a dump/restore so you
can solve the problems up front.
