Hello!
I posted you a message about slowness of creation users more than 500 000 (#4919). It seems there is no workaround of this problem because of using pg_auth flat file.
To override this problem is it possible to use LDAP authentification metod to identify each user and speed up system? How it will affect group roles for each user because we use groups roles to give Access to users to system objects? Because group roles will work only with postgres users not LDAP.
pgBouncer or pgPool uses Postgres users for connection pooling. Is there some more variants to use connection pooling without using postgres users?
