Description:

Pg database is not locked after password verification fails several times.

Correct, there is no such feature built-in, so there is no bug in something
that does not work.

If you want this feature you can integrate PostgreSQL with numerous
external authentication methods such as gssapi, ldap, radius or pam, all of
which can provide such functionality if set up right. You can also use
fail2ban or some simple log-tailing script that implements it.
