Granting of permissions on tables - Mailing list pgsql-sql

I have PostgreSQL v7.02 running on a HP-UX 11.00 box.  I as the owner of
some tables granted permissions to another user.  I executed the following
command from psql

GRANT ALL on <tables here> to <user2>;

after running the command I lost permissions to the tables once I exited
psql.  I had to run psql as the postgres user to correct the situation.

Is this a bug or desired behavior?  I would imagine since I owned the tables
and then granted permissions to another user, I wouldn't lose my
permissions.

Any help or explanation would be appreciated.

Thanks,
Scott Saltsgaver
