Password complexity/history - credcheck?

Hello.

Recently our security team have wanted to apply password complexity 
checks akin to Oracle's profile mechanism to PostgreSQL, checking that a 
password hasn't been used in x months etc, has minimum length, x special 
characters and x numeric characters, mixed case etc.

As far as I'm aware there's nothing part of the standard 'community 
edition' which gives us that, apart from passwordcheck - which doesn't 
give you a password history.

Can anyone recommend a good mechanism to accomodate this? Ideally we're 
looking for something well-established, reliable, and easily 
configurable. Does anything spring to mind?

A colleague has been looking around, and stumbled across 
https://github.com/MigOpsRepos/credcheck. Does anyone have any positive 
(or negative) experience with this? I'm happy to download and apply to a 
test database, obviously, but some indication of whether or not it's 
worth looking at first would be greatly appreciated. Is this something 
that the community would recommend?

Many thanks!
