BF animal malleefowl reported an failure in 001_password.pl

Hi,

I noticed one BF failure[1] when monitoring the BF for some other commit.

# Failed test 'authentication success for method password, connstr user=scram_role: log matches'
# at t/001_password.pl line 120.
# '2023-01-13 07:33:46.741 EST [243628:5] LOG: received SIGHUP, reloading configuration files
# 2023-01-13 07:33:46.742 EST [243662:1] [unknown] LOG: connection received: host=[local]
# 2023-01-13 07:33:46.744 EST [243662:2] [unknown] LOG: connection authorized: user=scram_role database=postgres application_name=001_password.pl
# 2023-01-13 07:33:46.748 EST [243662:3] 001_password.pl LOG: statement: SELECT $$connected with user=scram_role$$
# '
# doesn't match '(?^:connection authenticated: identity="scram_role" method=password)'
# Looks like you failed 1 test of 79.
[08:33:47] t/001_password.pl ........

After checking the test and log, I can see the test failed at the following code:
----
# For plain "password" method, all users should also be able to connect.
reset_pg_hba($node, 'all', 'all', 'password');
test_conn($node, 'user=scram_role', 'password', 0,
log_like =>
[qr/connection authenticated: identity="scram_role" method=password/]);
----

From the log, the expected "xxx method=password " log was not output, a simple
"connection authorized: user=scram_role database=postgres " was output Instead.
So it seems the connection happens before pg_ident.conf is actually reloaded ?
Not sure if we need to do something make sure the reload happen, because it's
looks like very rare failure which hasn't happen in last 90 days.
