initdb fails

Good day to you...

I am currently having a problen initializing database in HPUX11.0.
When I try to run initdb this is the result

The files belonging to this database system will be owned by user "calib".
This user must also own the server process.

The database cluster will be initialized with locale ja_JP.eucJP.

fixing permissions on existing directory /home/calib/data... ok

creating template1 database in /home/calib/data/base/1... ERROR:  invalid
input syntax for type "oid": "select cast(($1 + $2) as timestamp with time
zone)"

initdb: failed

I'm really having a hard time on why this happens. I hope you can reply
regarding this issue.

Thank you very much.
