by the test.  So, force both of them to be set from the MULTIBYTE
environment var.  This allows regress tests to be run successfully in
multibyte environments other than the compiled-in default.

like this one work now:

This fixes a few of the problems Hiroshi Inoue complained of, but
I have not touched the rewrite-related issues.

MyProcPid global variable is set to 0 when postgres starts as a command

not the process itself. As a result, parent sh gets core dumped in the
Wisconsin benchmark test.

Also made the same fix to int8smaller(), though there wasn't a symptom,
 and went through and verified that other pass-by-reference data types
 do the same thing. Not an issue for the by-value types.

instructions on how to install and use Multibyte support. Primarily
oriented toward Russian (Cyrillic) users.

foolish choices (ie, using nested-loop plans) on never-yet-vacuumed tables.
This is a hack, of course.  Keeping accurate track of these statistics
would be a cleaner solution, but it's far from clear that it'd be worth
the cost of doing so.  In any case we're not going to do that for 6.5.
In the meantime, this quick hack provides a useful performance improvement
in the regression tests and in many real-world scenarios.
