/contrib/unixdate: Broke in cvs tip.

I tried to use the unixdate contrib, and got the following:

attack=# \i unixdate.sql
psql:unixdate.sql:21: ERROR: ProcedureCreate: there is no builtin
function named "-"
psql:unixdate.sql:25: ERROR: Function 'abstime_datetime(int4)' does
not exist
Unable to identify a function that satisfies the given
argument types
You may need to add explicit typecasts
psql:unixdate.sql:29: ERROR: ProcedureCreate: there is no builtin
function named "-"
psql:unixdate.sql:33: ERROR: Function 'reltime_timespan(int4)' does
not exist
Unable to identify a function that satisfies the given
argument types
You may need to add explicit typecasts
attack=#

Any ideas? (I need SOMETHING that takes a unix timestamp and turns it
to timestamp. )

Thanks!
