Bug reference: 16522 Logged by: yi Ding Email address: abcxiaod@126.com PostgreSQL version: 10.13 Operating system: linux 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.
