Обсуждение: pgsql: Fix usage of char2wchar/wchar2char.
Log Message: ----------- Fix usage of char2wchar/wchar2char. Changes: - 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.
