After using PostgreSQL 8.1 and earlier versions for years, I'm suddenly
encountering a vexing problem. A certain kind of update and insert is
frequently reverting to its original condition after a day or two -- the
inserted record is gone and the updated one is back the way it was.
There seems to be no code in the application that could be doing this.
I know this is a long shot but is there any way the changes could be
getting rolled back automatically? I'm not using any explicit COMMIT,
ROLLBACK, or SAVEPOINT statements.

What is this certain kind of update or insert? If it's visible to
other database queries (that aren't in the same transaction), it's
been committed. I suspect there's something in the code that you
haven't found yet--or maybe some kind of restore procedure from an
earlier backup?
Can you provide a reproducible test case?
