Hello Chris, can not provide much help. But definitely the message sounds like case (1) (8.3 server accessing 7.4 files) I did encounter such with two occasions: a) used an old initdb version b) using an rc script that had hard coded path to the (old) data directory both cases seem not to apply in your case. BTW: you may check PG:VERSION file(s) in data directories to verify what version those directory are claiming to be.
