Oh? Ok, that's helpful.

It still eliminates the main potential use of auto-explain on production
sites, though, which is to turn it on only for specific operations.
I've never been able to make use of auto-explain for any real diagnostic
purpose on a production site, and I don't personally know anyone who has.

I recall bringing this up when auto-explain was first committed as a
fatal limitation in the module. And as far as I'm concerned, it has been.

Fixing this would clearly be complex; we don't currently have a system
which lets the superuser control which other users can change specific
parameters, even though that would be useful in a lot of contexts.
Presumably, making auto-explain would also require such a system of
grants, so it's not something we're fixing for 9.3, I'd imagine.

To get back to the original thread, though: I'm saying that "you can do
that with auto-explain" is zero justification to limit any of Greg's
work, because auto-explain isn't generally useful.
