No, PQping("host='127.0.0.1'") fails to reach a listen_addresses='::' server
on many systems. Here's what I thought Kondo was proposing:
--- a/src/bin/pg_ctl/pg_ctl.c
+++ b/src/bin/pg_ctl/pg_ctl.c
@@ -649,5 +649,9 @@ test_postmaster_connection(pgpid_t pm_pid, bool
do_checkpoint)
- /* If postmaster is listening
on "*", use localhost */
+ /* explanation here */
if (strcmp(host_str, "*") == 0)
strcpy(host_str,
"localhost");
+ else if (strcmp(host_str,
"0.0.0.0") == 0)
+ strcpy(host_str,
"127.0.0.1");
+ else if (strcmp(host_str, "::")
== 0)
+ strcpy(host_str, "::1");
