Thread: Migration from PG 7.1.3 to 8.1.1 with blobs

Hello,

I want to migrate a PostgreSQL db from 7.1.3 to PG db 8.1.1.
The db contains blobs. Some time ago, I used pg_dumplo to dump
and restore blobs. But in 8.1.1, I can not find anymore this
little program to do the job.

What could be the best way to migrate?
Thanks for your help.

Wow, that's a big jump.  Expect to find a few minor incompatibilities...

I think it's still in contrib/, but you really don't need it.  pg_dump
handles blobs just fine these days.  Just point 8.1's pg_dump at the
7.1 server.
