Ok, after Tatsuo and Peter have both said that building without locale
support should not use the locale support in the OS, and remembering my
6.5.3 experience of a year back, I decided to test it out completely. 
And I am wrong with respect to 7.1beta4.

For 7.1beta4 disabling locale will indeed work properly, at least on
RedHat 6.2.

Testing methodology:
1.)	Blow out entire PGDATA tree;
2.)	Initdb with locale-enabled backend;
3.)	Run regression with locale-enable binaries (locale=en_US);
4.)	Rebuild without --enable-locale;
5.)	Blow out entire PGDATA tree;
6.)	Initdb with non-locale backend;
7.)	Run regression with non-locale binaries.

Results:
For --enable-locale RPM's, pg_regress --schedule=parallel_schedule
produces:

With locale disabled:
All 76 tests passed.

So, there's the data.  This is different behavior from the 6.5.3
non-locale set I produced a year ago.  Is there interest in a non-locale
RPM distribution, or?  The locale enabled regression results fail due to
currency format and collation errors.  Diffs attached.  I'm not sure I
understand the select_views failure, either.  Locale used was en_US.

Comments?

The select_views delta looks like a sort-order issue as well; nothing
to worry about.

These deltas would go away if you allowed pg_regress to build a temp
installation in which it could force the locale to C.  Of course,
that doesn't presently work without a built source tree to install
from.  I wonder if it is worth adding a third operating mode to
pg_regress that would build a temp PGDATA directory but use the
already-installed bin/lib/share directories ...

Good.  I didn't see any difference -- but maybe that's because I went
cross-eyed.... :-)

Possibly.  If pg_regress uses a different port for postmaster, AND a
different PGDATA, you could run regression on a sandbox while a
production system was running, FWIW.  Since that's more of an RPM issue
than a core issue, I can do that third mode work, as I would be the
direct benefactor (unless someone else does it first, of course).

Both the locale and non-locale installation were from RPM, BTW, as I
wanted the least number of variables possible.
