The attached patch tries to add one more security hook on the initialization of PostgreSQL instance (InitPostgres()).
It gives the external security module a chance to initialize itself, and acquire credential of the client. I assumed the best place to initialize the module is just after the initialize_acl() invocation, if ESP is available. We have not discussed about this hook yet. So, I'd like to see any comments.
