Oh sorry, I misunderstood. Didn't realize you meant database users an not
an application user table implemented in Postgres.  I'll let others answer
that then because i'm not aware of a way to do that.

Consider using PAM authentication where you can insert any of already
existing password strength checks.
Or, maybe, LDAP auth where stuff will be enforced by LDAP server.

Thanks Adam, but here the requirement to enforce password polices while
creating to the users.

create user abc with password 'Password';

where it will test that the password entered should be according to the
company standard, while creation of users.
So please suggest.

If you're actually interested in having an extension which works like the
above, and want to work on porting it, i'd be more than happy to jump in
and help out where I can. I just don't have the free cycles to do it my
self at the moment.

Now on to your original question...Why wouldn't it be possible to create a
trigger on your users table to check the password being inserted, raise an
error if it does not meet your requirement, or hash it if it does and
continue the insert?  Seems pretty straight forward other than the
complexity of actually estimating how secure a password is.

Trigger or function which check the password strength is useful for me
