Hi
I got exactly the same error as Terry.
Using Redhat 6.2, AOLserver 3 final, PG 7.0.2, openacs 3.2.2b3 and the latest (downloaded today) pg driver.
Before this I had problems loading the datamodel because the language setting in "postgres.sql" was a lower case 'c', while PG or the driver (not sure which) was expecting 'C'. This is just FYI
Also nuke user failed with "Database operation "dml" failed"
Cheers
