The other LC_xxx settings will get fixed by GUC *only* if there are
explicit settings in postgresql.conf ... I don't think you can assume that.

You need to fix at least LC_MESSAGES, surely, if you want errors from
these processes suitably localized. Although in theory none of these
guys do any index operations and so should not need LC_COLLATE set,
it scares me to think of what might go wrong; probably best to fix
'em all.

Note that I am about to whack around the checkpointer and bgwriter, so
you might want to wait a day or two before you try to do this.

If those guys do not go through that variable-saving-and-restoring
routine, they are probably broken ipso facto. You sure they don't?

Sounds sufficient to me. All you are doing is implementing a substitute
for the Unix copy-on-fork behavior.
