Hi, thanks for your reply.

The problem that I showed occurs in following case for example.

1. user_1$ initdb -D /tmp/test
2. user_1$ sudo chown -R user_2:user_2 /tmp/test
3. user_2$ pg_ctl -D /tmp/test -w start  <-- problem occurs!
(Because, there is no role for user_2 in "/tmp/test". But server starting.)

Yes, I agree.
I think role and database(postgres) existence check is necessary before
starting postmaster.
# Or improve the connection test way in test_postmaster_connection().
