bb36c51fcd Fix several bugs in tsvectorin, including crash due to uninitialized field and 
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.

f551348417 Clarify example of planner cost computation, per a suggestion from 
James Shaw.  Also update a couple of examples to reflect 8.3's improved
plan-printing code.

3e17ef1cfa Adjust ts_debug's output as per my proposal of yesterday: show the 
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.

6088bfb8b6 Create a quick-and-dirty list of known migration issues for pre-8.3 
users of tsearch.  This isn't meant to be permanent documentation,
but to call out the areas that need either fixing or real documentation.

f1c87830b5 Add a useless return statement to suppress a warning seen with some 
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.

1ea47dd8cb Fix shared tsvector/tsquery input code so that we don't say "syntax error in 
tsvector" when we are really parsing a tsquery.  Report the bogus input,
too.  Make styles of some related error messages more consistent.

dfc6f130b4 Editorial overhaul for text search documentation. Organize the info 
more clearly, improve a lot of unclear descriptions, add some missing
material.  We still need a migration guide though.

41a312a1f6 Add a note pointing out that you can't log to syslog without tweaking 
the syslog configuration file (at least not on most known Unixen).
I dunno why we hadn't had that info in the docs all along ...

638bd34f89 Found another small glitch in tsearch API: the two versions of ts_lexize() 
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.

26cbf791ec Add missing entry for PG_WIN1250 encoding, per gripe from Pavel Stehule. 
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.

6efae5bf2a Another round of editorialization on the text search documentation. 
Notably, standardize on using "token" for the strings output by a parser,
while "lexeme" is reserved for the normalized strings produced by a
dictionary.

56303abff0 Tweak toast-related logic in heapam.c so that the toaster is only invoked 
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.

fb631dba2a Include NOLOGIN roles in the 'flat' password file. In the original 
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.
