categories, as per discussion. asciiword (formerly lword) is still
ASCII-letters-only, and numword (formerly word) is still the most general
mixed-alpha-and-digits case. But word (formerly nlword) is now
any-group-of-letters-with-at-least-one-non-ASCII, rather than all-non-ASCII as
before. This is no worse than before for parsing mixed Russian/English text,
which seems to have been the design center for the original coding; and it
should simplify matters for parsing most European languages. In particular
it will not be necessary for any language to accept strings containing digits
as being regular "words". The hyphenated-word categories are adjusted
similarly.

This removes the direct dependency on shell32.dll and user32.dll, which
eats a lot of "desktop heap" for each backend that's started. The
desktop heap is a very limited resource, causing backends to no
longer start once it's been exhausted.
We still have indirect depdendencies on user32.dll through third party
libraries, but those can't easily be removed.

miscomputation of required palloc size. The crash could only occur if the
input contained lexemes both with and without positions, which is probably not
common in practice. The miscomputation would definitely result in wasted
space. Also fix some inconsistent coding around alignment of strings and
positions in a tsvector value; these errors could also lead to crashes given
mixed with/without position data and a machine that's picky about alignment.
And be more careful about checking for overflow of string offsets.
Patch is only against HEAD --- I have not looked to see if same bugs are
in back-branch contrib/tsearch2 code.
active dictionary and its output lexemes as separate columns, instead
of smashing them into one text column, and lowercase the column names.
Also, define the output rowtype using OUT parameters instead of a
composite type, to be consistent with the other built-in functions.
versions of gcc (I'm seeing it with Apple's gcc 4.0.1). I think the
reason we did not see this before was that the assert() macros in the
regex code were all no-ops till recently.
are really redundant, since we invented a regdictionary alias type.
We can have just one function, declared as taking regdictionary, and
it will handle both behaviors. Noted while working on documentation.
Also enable translation of PG_WIN874, which certainly seems to have an
obvious translation now, though maybe it did not at the time this table's
ancestor was created.
Notably, standardize on using "token" for the strings output by a parser,
while "lexeme" is reserved for the normalized strings produced by a
dictionary.
when relkind = RELKIND_RELATION. This syncs these tests with the Asserts
in tuptoaster.c, and ensures that we won't ever try to, for example,
compress a sequence's tuple. Problem found by Greg Stark while stress-testing
with much-smaller-than-normal page sizes.
coding this was seen as useless, but the problem with not including them
is that the error message will often be something about authentication
failure, rather than the more helpful one about 'role is not permitted
to log in'. Per discussion.
