debug logs: query: rollback

(With 7.0.3, going to 1.1 RSN'ish.)

I've just stared looking at logs and I'm getting lines in the log:

query: rollback

does this mean that a transaction has failed? I'm not seeing any other
error messages (mind you, I need to check my scripts and see what they
are loggingas errors).

usr/local/pgsql/bin/postmaster: reaping dead processes...
/usr/local/pgsql/bin/postmaster: CleanupProc: pid 13874 exited with status 0
