Hi everyone,

I found typo in comment auto_explain.c line 282 (/* Enable per-node instrumentation iff log_analyze is required. */).

Not 'iff' but 'if'.

It's short for "if and only if". See https://en.wikipedia.org/wiki/If_and_only_if.

There was some previous discussion on pgsql-hackers on whether that usage common enough, although I don't find the thread right now. You're not the first one to think it's a typo :-).
