- pg_wchar and wchar_t could have different size, so char2wchar
doesn't call pg_mb2wchar_with_len to prevent out-of-bound
memory bug
- make char2wchar/wchar2char symmetric, now they should not be
called with C-locale because mbstowcs/wcstombs oftenly doesn't
work correct with C-locale.
- Text parser uses pg_mb2wchar_with_len directly in case of
C-locale and multibyte encoding
Per bug report by Hiroshi Inoue <inoue@tpf.co.jp> and
following discussion.
Backpatch up to 8.2 when multybyte support was implemented in tsearch.
Fix string's length calculation for recoding, fix strlower() to avoid wrong
assumption about length of recoded string (was: recoded string is no greater
that source, it may not true for multibyte encodings)
Thanks to Thomas H. <me@alternize.com> and Magnus Hagander <mha@sollentuna.net>
comment line where output as too long, and update typedefs for /lib
directory. Also fix case where identifiers were used as variable names
in the backend, but as typedefs in ecpg (favor the backend for
indenting).
Backpatch to 8.1.X.
- 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'
