How do I configure postgres to lock a user's account after X failed login attempts, where X is an arbitrary number.

Also is there a way to limit the number of concurrent connections on a per account basis?

Don't think there is a way to do that.
Perhaps using an authentication mechanism that supports that and then using
it to connect to Postgres..

Don't think there is an option for that either.

ALTER ROLE <role> CONNECTION LIMIT <number>;

The usual suggestion is to use PAM if you want a customized login
policy.

Yeah, an external authentication tool can probably do that. The internal
ones (password, md5, and crypt) won't.

Sure, there is one:

ALTER ROLE your-user WITH CONNECTION LIMIT x;

See http://www.postgresql.org/docs/8.4/interactive/sql-alterrole.html
for more details.
