Re: sync the data's from catalog table

Hi,

Whenever the postgres user is trying to modify the user account's password
column in pg_authid table, we need to maintain a trigger in catalog table
(pg_authid) where it pop up the the "password column has been restricted
and it should not be modified". Is there any possible for the above
scenario in postgres? if it there please guide me how to proceed on this.
and one more question, Can we restrict the postgres user to not modify the
pg_authid table. Please share your thoughts on it.

Thanks
