This adds collation support for columns and domains, a COLLATE clause
to override it per expression, and B-tree index support.

304845075c Use array_contains_nulls instead of ARR_HASNULL on user-supplied arrays.
This applies the fix for bug #5784 to remaining places where we wish
to reject nulls in user-supplied arrays.  In all these places, there's
no reason not to allow a null bitmap to be present, so long as none of
the current elements are actually null.

I did not change some other places where we are looking at system catalog
entries or aggregate transition values, as the presence of a null bitmap
in such an array would be suspicious.

29d2f86a31 Allow zero-dimensional (ie, empty) arrays in contrib/ltree operations.
The main motivation for changing this is bug #4921, in which it's pointed out
that it's no longer safe to apply ltree operations to the result of
ARRAY(SELECT ...) if the sub-select might return no rows.  Before 8.3,
the ARRAY() construct would return NULL, which might or might not be helpful
but at least it wouldn't result in an error.  Now it returns an empty array
which results in a failure for no good reason, since the ltree operations
are all perfectly capable of dealing with zero-element arrays.

As far as I can find, these ltree functions are the only places where zero
array dimensionality is rejected unnecessarily.

Back-patch to 8.3 to prevent behavioral regression of queries that worked
in older releases.

8eee65c996 ltree support for multibyte encodings. Patch was made by
laser <laserlist@pgsqldb.com> with some editorization by me.

f8c4d7db60 Restructure some header files a bit, in particular heapam.h, by removing some
unnecessary #include lines in it.  Also, move some tuple routine prototypes and
macros to htup.h, which allows removal of heapam.h inclusion from some .c
files.

For this to work, a new header file access/sysattr.h needed to be created,
initially containing attribute numbers of system columns, for pg_dump usage.

While at it, make contrib ltree, intarray and hstore header files more
consistent with our header style.

8e5a10d46c This patch makes the error message strings throughout the backend
more compliant with the error message style guide. In particular,
errdetail should begin with a capital letter and end with a period,
whereas errmsg should not. I also fixed a few related issues in
passing, such as fixing the repeated misspelling of "lexeme" in
contrib/tsearch2 (per Tom's suggestion).

25c00833cb Add defenses against nulls-in-arrays to contrib/ltree. Possibly it'd
be useful to actually do something with nulls, rather than reject them,
but I'll just close the hole for now.

0bd61548ab Solve the 'Turkish problem' with undesirable locale behavior for case
conversion of basic ASCII letters.  Remove all uses of strcasecmp and
strncasecmp in favor of new functions pg_strcasecmp and pg_strncasecmp;
remove most but not all direct uses of toupper and tolower in favor of
pg_toupper and pg_tolower.  These functions use the same notions of
case folding already developed for identifier case conversion.  I left
the straight locale-based folding in place for situations where we are
just manipulating user data and not trying to match it to built-in
strings --- for example, the SQL upper() function is still locale
dependent.  Perhaps this will prove not to be what's wanted, but at
the moment we can initdb and pass regression tests in Turkish locale.

71e1f531d3 Please apply patches for contrib/ltree.
ltree_73.patch.gz - for 7.3 :
        Fix ~ operation bug: eg '1.1.1' ~ '*.1'

ltree_74.patch.gz - for current CVS
    Fix ~ operation bug: eg '1.1.1' ~ '*.1'
    Add ? operation
    Optimize index storage

Last change needs drop/create all ltree indexes, so only for 7.4
