pgbouncer バージョン 1.7.2
psql (9.5.6)
PgBouncer で auth_hba_file (/var/lib/pgsql/9.5/data/pg_hba.conf) を使用してみます。
pgbouncer.ini の設定
postgres = host=localhost port=5432 dbname=postgres user=postgres
test = host=localhost port=5432 dbname=test user=test
[pgbouncer]
logfile = /var/log/pgbouncer/pgbouncer.log
pidfile = /var/run/pgbouncer/pgbouncer.pid
listen_addr = *
listen_port = 6432
auth_type = hba
auth_hba_file = /var/lib/pgsql/9.5/data/pg_hba.conf
admin_users = postgres
stats_users = stats, postgres
pool_mode = session
server_reset_query = DISCARD ALL
max_client_conn = 100
default_pool_size = 20
猫pg_hba.conf | grep -v "#" | grep -v "^$"
local all all trust
host all all 127.0.0.1/32 trust

しかし、pg_hba.confを使用して（PgBouncerを使用して）postgresqlに接続できません
誰か助けてくれませんか？auth_hba_file の使用例を教えてください。ありがとう
構成を変更しました：
