Unable to get metrics from databases

[Yeroha]

What did you do?
I installed postgres_exporter 0.16.0 linux. I have 2 databases: test_db_1, test_db_2. Trying get metrics from tables pg_stat_user_tables for my databases, but i see metrics from only postgres DB. Inserted --auto-discover-databases to config file, but not working. User postgres_exporter has privileges on these databases
Why i'm not see metrics from DBs?

• postgres_exporter version:

  0.16.0

• PostgreSQL version:

  16.7.1
