Make regression tests locale-proof by setting some locale categories 

to C at run-time, and providing alternative output files for different
sort orders.

<title>Locale differences</title>
<para>
The tests expect to run in plain <quote>C</quote> locale. This
should not cause any problems when you run the tests against a
temporary installation, since the regression test driver takes care
to start the server in C locale. However, if you run the tests
against an already-installed server that is using non-C locale settings,
you may see differences caused by varying rules for string sort order,
formatting of numeric and monetary values, and so forth.
If you run the tests against an already-installed server that was
initialized with a collation order locale different than C then
there may be differences due to sort order and follow-up
failures. The regression test suite is set up to handle this
problem by providing alternative result files that together are
known to handle a large number of locales. For example, for the
<quote>char</quote> test, the expected file
<filename>char.out</filename> handles the C and POSIX locales,
and the file <filename>char_1.out</filename> handles many other
locales. The regression test driver will automatically pick the
best file to match against when checking for success and for
computing failure differences. (This means that the regression
tests cannot detect whether the results are appropriate for the
configured locale. The tests will simply pick the one result
file that works best.)
</para>
<para>
In some locales the resulting differences are small and easily checked by
inspection. However, in a locale that changes the rules for formatting
of numeric values (typically by swapping the usage of commas and
decimal points), entry of some data values will fail, resulting in
extensive differences later in the tests where the missing data values
are supposed to be used.
If for some reason the existing expected files do not cover some
locale, you can add a new file. The naming scheme is
<literal><replaceable>testname</>_<replaceable>digit</>.out</>.
The actual digit is not significant. Remember that the
regression test driver will consider all such files to be equally
valid test results. If the test results are platform-dependent,
the technique described in <xref linkend="regress-platform">
should be used instead.
