Too bad we didn't do it *before* doing a lot of translation work :-(.

Yes, I agree that a pass of rationalizing the error messages would be
useful.  Might want to think about that old bugaboo, error codes,
while we're at it.  Also the perennial complaint that "ERROR" and
"DEBUG" macros tend to conflict with other things.  As long as we're
going to touch many/all of the elog() calls, couldn't we try to clean
up all these issues?

Given that 'x' and "x" mean very different things in SQL, I think that
the first form is just plain wrong when an identifier is involved.
Unfortunately a lot of older code uses that style.  I've tried to use
double quotes in new messages, but have restrained myself from wholesale
changes of existing messages.

Sounds like a plan to me: put together a style guide first, and then
make a pass through the code to try to implement it.
