Forum OpenACS Q&A: OACS 3.2.5 on Postgres 7.2

I asked this question a couple days ago and got no response. Here's what I see from searching the bboard:

char/varchar problems:

(this is the problem you ran into, and suggests a better solution)

general, including non-db fixes to 3.2.5:

So we have at least 6 people running 3.2.5 on PG 7.2, who have reported around half a dozen "core" errors. You'll probably see more in parts of the toolkit these people haven't explored, but it doesn't look unmanagable by any means.
