How to set an expiration date for a WHOLE user account

Hi,
I'm wonder how I can disable a user (without droping of course). Is there a
way to set an expiration date to prevent logins after that date?

I know the VALID UNTIL clause of CREATE USER command, but it is about the
password only.
I think something similar but regarding the whole user account.

Thanks,

It is not about password only. Once current date is beyond the valid date
you set, the user can never get authorized ok anymore.

He's right, you're not: that check is only applied in the
password-based authorization path.

This has always seemed a bit bogus to me too --- would not object to
a well-thought-out patch to change it.

Re: How to set an expiration date for a WHOLE user account

Hi.
Concerning Egy�d's question, I also wanted to ask about setting expiration
date for database. But, I would like to set validity in sense of certain
actions.
For example, I would like to prevent adding new records after expiration,
but would allow viewing existing records....
Is there any way to acomplish that?
Greetings,
Zlatko

Possibly you could do what you want by using AFTER triggers on all of the
tables. This will only be practical if the users with update access do
not own the tables.

If we add a "VALID UNTIL" column in pg_hba.conf, then will work for all
authorization path?
