No, no, and no. A 7.2.anything server would flat out refuse to start in
a 7.3.* database (because it checks PG_VERSION). You might have been
using 7.3 client-side code to talk to the 7.2 server, but that wouldn't
cause this sort of failure.
A possible quick-and-dirty solution is "VACUUM pg_database" (issued from
any of the databases that you can get into). If that doesn't work then
you've got serious problems :-(
