629b3af27d Convert contrib modules to use the extension facility.
This isn't fully tested as yet, in particular I'm not sure that the
"foo--unpackaged--1.0.sql" scripts are OK.  But it's time to get some
buildfarm cycles on it.

sepgsql is not converted to an extension, mainly because it seems to
require a very nonstandard installation process.

1753337cf5 Improve psql's tabular display of wrapped-around data by inserting markers
in the formerly-always-blank columns just to left and right of the data.
Different marking is used for a line break caused by a newline in the data
than for a straight wraparound.  A newline break is signaled by a "+" in the
right margin column in ASCII mode, or a carriage return arrow in UNICODE mode.
Wraparound is signaled by a dot in the right margin as well as the following
left margin in ASCII mode, or an ellipsis symbol in the same places in UNICODE
mode.  "\pset linestyle old-ascii" is added to make the previous behavior
available if anyone really wants it.

In passing, this commit also cleans up a few regression test files that
had unintended spacing differences from the current actual output.

90e3f2aca7 Replace the now-incompatible-with-core contrib/tsearch2 module with a
compatibility package.  This supports importing dumps from past versions
using tsearch2, and provides the old names and API for most functions
that were changed.  (rewrite(ARRAY[...]) is a glaring omission, though.)

22505f4703 Add thesaurus dictionary which can replace N>0 lexemes by M>0 lexemes.
It required some changes in lexize algorithm, but interface with
dictionaries stays compatible with old dictionaries.

38c4fe87ac Significantly improve ranking:
1) rank_cd now use weight of lexemes
2) rank_cd and rank can use any combination of normalization methods:
        no normalization
        normalization by log(length of document)
        -----/------- by length of document
        -----/------- by number of unique word in document
        -----/------- by log(number of unique word in document)
        -----/------- by number of covers (only rank_cd)

Improve cover's search.

5e2707c45f Snowball multibyte. It's a pity, but snowball sources is very diferent for multibyte and
singlebyte encodings, so we should have snowball for every encodings.

I hope that finalize multibyte support work in tsearch2, but testing is needed...

c52795d18a Text parser rewritten:
- supports multibyte encodings
        - more strict rules for lexemes
        - flex isn't used
Add:
        - tsquery plainto_tsquery(text)
          Function makes tsquery from plain text.
        - &&, ||, !! operation for tsquery for combining
          tsquery from it's parts:  'foo & bar' || 'asd' => 'foo & bar | asd'

0645663e6c New features for tsearch2:
1 Comparison operation for tsquery
2 Btree index on tsquery
3 numnode(tsquery) - returns 'length' of tsquery
4 tsquery @ tsquery, tsquery ~ tsquery - contains, contained for tsquery.
  Note: They don't gurantee exact result, only MAY BE, so it
  useful only for speed up rewrite functions
5 GiST index support for @,~
6 rewrite():
        select rewrite(orig, what, to);
        select rewrite(ARRAY[orig, what, to]) from tsquery_table;
        select rewrite(orig, 'select what, to from tsquery_table;');
7 significantly improve cover algorithm

bb3cce4ec9 Add E'' syntax so eventually normal strings can treat backslashes
literally.

Add GUC variables:

        "escape_string_warning" - warn about backslashes in non-E strings
        "escape_string_syntax" - supports E'' syntax?
        "standard_compliant_strings" - treats backslashes literally in ''

Update code to use E'' when escapes are used.

0b1ee9b5a3 fix hlfinditem function. Thanks to "Stphane Bidoul" <stephane.bidoul@softwareag.com>.
The 'word' variable there is initialised from
the prs->words array, but immediately after,
that array may be reallocated, thus leaving
word pointing to unallocated memory.
