Uh-oh, there's a thread on the standard OpenACS forum in which someone describes PG 7.1.1 crashing on their attempts to install 3.2.5.
Uh-oh.
Uh-oh.
I'll be back in town late tomorrow, in effect back to work Tuesday. If no one's contacted the PG developers about this by then (or if they've not run into it themselves) I'll ping Tom Lane then.
Uh-oh...
