http://www.postgresql.org/idocs/index.php?datatype-datetime.html says:
The types abstime and reltime are lower precision types which are used
internally. You are discouraged from using any of these types in new
applications and are encouraged to move any old ones over when
appropriate. Any or all of these internal types might disappear in a
future release.
Don't they?
