In this function: static bool test_postmaster_connection(bool do_checkpoint)
This code will never succeed: snprintf(connstr, sizeof(connstr), "dbname=postgres port=%s connect_timeout=5", portstr); for (i = 0; i < wait_seconds; i++) { if ((conn = PQconnectdb(connstr)) != NULL && (PQstatus(conn) == CONNECTION_OK || PQconnectionNeedsPassword(conn))) { PQfinish(conn); success = true; break; } Because pg_hba.conf has this: # TYPE DATABASE USER CIDR-ADDRESS METHOD # IPv4 local connections: host all all 127.0.0.1/32 trust # IPv6 local connections: host all all ::1/128 trust to allow connections from the local machine. (A password is not needed to connect, so the code always fails). -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
