I will be converting from PostgreSQL 8.1.4 to 8.2.4. Is it OK to do

Remember that port 1234 is PostgreSQL 8.1.4 and port 5678 is
PostgreSQL 8.2.4.
Should be fine, as long as you ensure that the pg_dump you use, is the
one from your 8.2.4 installation, and not the 8.1.4 version.
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.
