Two things might help:
1) Upgrade to the latest CanIt (2.1a), because earlier versions seemed
to trigger this bug in PostgreSQL.
2) Upgrade to the latest version of PostgreSQL (7.4.3 as of this writing.)
If you upgrade from PostgreSQL earlier than 7.4, be aware that you must
dump all your databases with the old version *before* starting the upgrade.

David.
