Re: BUG #16049: log_line_prefix=%a and log_connections - application_name missing

"will do what you want." Not exactly - I want it to appear according
to my log_line_prefix - 4 ex. ='%t|%p|%a|%d|%u|%h| '
I've used that patch on 9.5.19

In elog.c there's : const char *appname = application_name; // line 2357
other cases have : const char *username = MyProcPort->user_name;
After adding 'MyProcPort->' to %a case '|psql|' shows up like I
wanted .. but connection process Segfaults :/

I've tracked it to postinit.c - process_startup_options() - this loop
: while (gucopts) {...}

gucopts = list_head(port->guc_options);
ereport(LOG, (errmsg(" +++ process_startup_options : [%s] ",
gucopts))); // adding this line returns :

Sorry 4 nagging , any pointers much appreciated
