This is the main motive behind the patch. Developer options aren't shown in postgresql.conf.sample, which it seems like sometimes people read through quickly, setting a whole bunch of options that sound good, sometimes including this one. And in the best case they then ask on -performance why their queries are slow and we tell them to turn it back off to fix their issues. This changes to no longer put it in .sample, and calling it a "dev" option seems to be the classification and mechanism by which to do that. -- Justin ps, Maybe you saw that I'd already resent without including the accidental junk hunks.
