It's been two weeks and I haven't seen anyone report problems similar to what I had and described above. That can that either nbbody read or payed attention to this thread or it's only happenning with me.
However, I can consistently reproduce backend crashes by simply pg_dumping and reloading the OpenACS datamodel and some data in three different machines running different versions of PostgreSQL 7.
I don't know about you all, but this scares the heck out of me. What other ways are there to backup a PG database?
