If people want to do that kind of thing (I'm undecided whether the
complexity is worth it), then make it a different API. The pg_log_*
calls are for writing formatted output. They normalized existing
hand-coded patterns at the time. We can wrap another API on top of them
that does flow control and output. The pg_log_* stuff is more on the
level of syslog(), which also just outputs stuff. Nobody is suggesting
that syslog(LOG_EMERG) should exit the program automatically. But you
can wrap higher-level APIs such as ereport() on top of that that might
do that.
