I think we need frontend facilities that look like the backend facilities, so try/catch blocks, on-exit callbacks, and whatever else there is. Otherwise code reuse is going to continue to be annoying.
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.
