help: collation support on Windows

According to the online documentation, the APIs are there:

Now we'd need someone brave try to make it work. The starting point
would be to define HAVE_LOCALE_T and then make it build. Microsoft has
all the relevant functions and types with an underscore in front
(_strcoll_l, etc.), so some extra #defining will probably be necessary.

Also, initdb will need to be patched to get a list of OS locales to
populate the pg_collation catalog with.

Finally, a regression test customized for Windows, but I can help with
that later.

What is the equivalent of "locale -a"?

cheers

There isn't a command that I know of, but the API function you
probably need is EnumSystemLocales.

Yeah. If you want example code, you can probably lift something from
the old pginstaller project on pgfoundry - we use that code to
populate the dropdown box for initdb there.

OK, I got that working now. Patch attached.

That still needs work, but you can run CREATE COLLATION manually.

If you doctor the existing linux test to create appropriately named
collations before running the actual tests, and you hack the
vcregress.pl driver script to run the tests in UTF8 instead of
SQL_ASCII, then all the tests except the Turkish case conversion tests
pass. So looks pretty good so far.
