NO WARRANTY !!!!!!!!!!!!!!!!!!!!!!!!!!!!!! - -Instalation: ------------- -1) Change three affected files in source directories - (I don't have time to create proper patch diffs, I don't know how) -2) Compile with enabled locale and multibyte set to LATIN2 -3) Setup properly your instalation, do not forget to create locale - variables in your profile (environment). Ex. (may not be exactly true): - LC_ALL=cs_CZ.ISO8859-2 - LC_COLLATE=cs_CZ.ISO8859-2 - LC_CTYPE=cs_CZ.ISO8859-2 - LC_MONETARY=cs_CZ.ISO8859-2 - LC_NUMERIC=cs_CZ.ISO8859-2 - LC_TIME=cs_CZ.ISO8859-2 -4) You have to start the postmaster with locales set! -5) Try it with Czech language, it have to sort -5) Install ODBC driver for PgSQL into your M$ Windows -6) Setup properly your data source. Include this line in your ODBC - configuration dialog in field "Connect Settings:" : - SET CLIENT_ENCODING = 'WIN1250'; -7) Now try it again, but in Windows with ODBC. - -Description: ------------- -- Depends on proper system locales, tested with RH6.0 and Slackware 3.6, - with cs_CZ.iso8859-2 loacle -- Never try to set-up server multibyte database encoding to WIN1250, - always use LATIN2 instead. There is not WIN1250 locale in Unix -- WIN1250 encoding is useable only for M$W ODBC clients. The characters are - on thy fly re-coded, to be displayed and stored back properly - -Important: ----------- -- it reorders your sort order depending on your LC_... setting, so don't be - confused with regression tests, they don't use locale -- "ch" is corectly sorted only in some newer locales (Ex. RH6.0) -- you have to insert money as '162,50' (with comma in aphostrophes!) -- not tested properly diff --git a/doc/README.mb.jp b/doc/README.mb.jp deleted file mode 100644 index 7cafb2426e..0000000000 --- a/doc/README.mb.jp +++ /dev/null @@ -1,814 +0,0 @@ -PostgreSQL 7.3 multi-byte (MB) support README 2002/10/21 $B:n@.(B - - $B@P0fC#IW(B - ishii@postgresql.org - -$B"#$O$8$a$K(B - - PostgreSQL $B$K$*$1$k%^%k%A%P%$%H%5%]!<%H$O0J2<$N$h$&$JFCD'$r;}$C$F$$$^$9!%(B - - 1. $B%^%k%A%P%$%HJ8;z$H$7$F!$F|K\8l!$Cf9q8l$J$I$N3F9q$N(B EUC$B!$(BUnicode$B!$(B - mule internal code, ISO-8859-* $B$,%G!<%?%Y!<%9:n@.;~$KA*Br2DG=!%(B - $B%G!<%?%Y!<%9$K$O$3$N%(%s%3!<%G%#%s%0$N$^$^3JG<$5$l$^$9!%(B - 2. $B%F!<%V%kL>$K%^%k%A%P%$%HJ8;z$,;HMQ2DG=(B - 3. $B%+%i%`L>$K%^%k%A%P%$%HJ8;z$,;HMQ2DG=(B - 4. $B%G!<%?$=$N$b$N$K$b%^%k%A%P%$%HJ8;z$,;HMQ2DG=(B - 5. $B%^%k%A%P%$%HJ8;z$N@55,I=8=8!:w$,;HMQ2DG=(B - 6. $B%^%k%A%P%$%HJ8;z$N(B LIKE $B8!:w$,;HMQ2DG=(B - 7. character_length(), position(), substring() $B$J$I$NJ8;zNs4X?t$G(B - $B$N%^%k%A%P%$%H%5%]!<%H(B - 8. $B%U%m%s%H%(%s%IB&$N%(%s%3!<%G%#%s%0$,%P%C%/%(%s%IB&$H0[$k>l9g$K!$(B - $B<+F0E*$K%(%s%3!<%G%#%s%0JQ49$r9T$J$$$^$9!%(B - 9. $B%f!<%6Dj5A$N%(%s%3!<%G%#%s%0JQ49$r:n@.2DG=!%(B - - $B%^%k%A%P%$%H%5%]!<%H$,07$&$3$H$N$G$-$k%(%s%3!<%G%#%s%0$O0J2<$K$J$j$^(B - $B$9!%(B - - SQL_ASCII ASCII - EUC_JP $BF|K\8l(B EUC - EUC_CN GB $B$r%Y!<%9$K$7$?CfJ8(BEUC$B!%(Bcode set 2 $B$O(B - SS2+2$B%P%$%H%3!<%I(B = 3$B%P%$%HI=8=$G$9!%(B - EUC_KR $B4Z9q8l(B EUC$B!%(B - JOHAB $B%O%s%0%k%Y!<%9$N4Z9q8l(BEUC. - EUC_TW $BBfOQ$N(B EUC$B!%(Bcode set 2 $B$O(B - SS2+$BLLHV9f(B+2$B%P%$%H%3!<%I(B = 4$B%P%$%HI=8=$G$9!%(B - UNICODE UTF-8$B!%$?$@$7%5%]!<%H$9$k$N$O(B UCS-2 $B$NHO0O!$(B - $B$9$J$o$A(B 0xffff $B$^$G$G$9!%(B - MULE_INTERNAL mule $B$NFbIt%3!<%I!%$?$@$7!$(BType N $B$NITDjD9J8;z$O(B - $B%5%]!<%H$7$F$$$^$;$s!%(B - LATIN1 $B$+$i(B LATIN10$B$^$G(B - ISO_8859_1 $B$+$i(B 16$B$^$G(B - $B%-%j%kJ8;z(B KOI8(KOI8-R), WIN(CP1251), ALT(CP866)$B$r%5%]!<%H(B - $B$7$F$$$^$9!%$b$A$m$s(B ISO 8859-5 $B$b;HMQ2DG=$G$9!%(B - $B$3$N>l9g!$(B"LATIN5" $B$H$7$F;XDj$7$F2<$5$$!%(B - WIN1256 $B%"%i%V=t9q8l(BWindows$BMQ%(%s%3!<%G%#%s%0(B. - TCVN $B%Y%H%J%`8l(B."ABC"$B$d(B"VSCII"$B$b;HMQ2DG=(B. - WIN874 $B%?%$8l(B. - - $B%U%m%s%H%(%s%IB&$G$O$5$i$K0J2<$N%(%s%3!<%G%#%s%0$,;HMQ$G$-$^$9!%(B - - SJIS $B%7%U%H(BJIS(MS932$B$H$[$\8_49(B) - BIG5 $BBfOQ$d9a9A$G;HMQ$5$l$F$$$kCf9q8l!%(BEUC_TW$B$H8_49(B - $B@-$,$"$j$^$9!%(B - GBK Windows-936 - UHC Windows-949 - WIN1250 Windows-1250 - GB18030 GB18030 - -$B"#F|K\8l$r;HMQ$9$k$3$H$N$G$-$k%(%s%3!<%G%#%s%0(B - - $BA*Br$NL\0B$H$7$F$O!$1Q8l$HF|K\8l$7$+;H$o$J$$>l9g$O(B EUC_JP($BF1MM$K!$Cf(B - $B9q8l$7$+;H$o$J$$>l9g$O(B EUC_CN... $B$J$I$H$J$j$^$9(B)$B!$$=$NB>$N8@8l$b;H$$$?(B - $B$$>l9g$O(B UNICODE $B$b$7$/$O(B MULE_INTERNAL $B$H$J$k$G$7$g$&!%(B - - $BCm0U!'(BMULE_INTERNAL $B$rA*$V$H!$$?$/$5$s$NJ8;z=89g$KBP1~$G$-$FJXMx$G$9(B - $B$,!$@55,I=8=$GJ#?t$NJ8;z=89g$K$^$?$,$k$h$&$JHO0O;XDj(B($B$?$H$($P!$(B[a-$BHO(B] - $B$H$+!$(B[abc$BHO0O(B]$B$N$h$&$J(B)$B$O;H$($^$;$s!%J#?t$NHO0O;XDj$G0[$J$kJ8;z=89g(B - $B$r;H$&$N$O9=$$$^$;$s(B($B$?$H$($P(B [abc][$BHO(B-$B0O(B])$B!%$^$?!$(B[^a] $B$N$h$&$JI=8=(B - $B$O!$(B"a" $B$NB0$9$kJ8;z=89g(B($B$3$N>l9g!$(BUS-ASCII)$B$K$*$$$F(B "a" $B0J30$G$"$k(B - $B$3$H$rI=$7$^$9!%7h$7$F4A;z$dJ?2>L>$J$I(B "a" $B0J30$r$9$Y$FI=$9$o$1$G$O(B - $B$J$$$3$H$KCm0U$7$F2<$5$$!%(B - -$B"#%$%s%9%H!<%k(B - - PostgreSQL 7.3$B$+$i$O(Bconfigure$B$N%*%W%7%g%s;XDj$NM-L5$K4X$o$i$:!$%^%k(B - $B%A%P%$%H%5%]!<%H$,M-8z$K$J$C$F$$$^$9$N$G!$FC$K(Bconifgure$B;~$K%^%k%A%P(B - $B%$%HMQ$NFCJL$J%*%W%7%g%s$r;XDj$9$kI,MW$O$"$j$^$;$s!%(B - -$B"#(Binitdb/createdb/create database $B$K$*$1$k%(%s%3!<%G%#%s%0$N;XDj$K$D$$$F(B - - initdb $B$G$O0J2<$N%*%W%7%g%s$G%(%s%3!<%G%#%s%0$,;XDj$G$-$^$9!%(B - - -E $B%(%s%3!<%G%#%s%0(B - --encoding=$B%(%s%3!<%G%#%s%0(B - - $B$3$3$G;XDj$7$?%(%s%3!<%G%#%s%0$O!$0J8e(B createdb/create database $B$G%((B - $B%s%3!<%G%#%s%0$r>JN,$7$?>l9g$K@_Dj$5$l$k%(%s%3!<%G%#%s%0$K$J$j$^$9!%(B - -E $B$^$?$O(B --encoding $B%*%W%7%g%s$r>JN,$7$?>l9g$O!$%(%s%3!<%G%#%s%0$H(B - $B$7$F(BSQL_ASCII$B$,:NMQ$5$l$F$7$^$&$N$G!$F|K\8l$r%G%U%)%k%H$G;HMQ$9$k>l(B - $B9g$O!$(B - - -E EUC_JP - - $B$"$k$$$O(B - - --encoding=EUC_JP - - $B$H$7$FI,$:L@<(E*$K%(%s%3!<%G%#%s%0$r;XDj$7$F$/$@$5$$!%(B - - $B$J$*!$(BPostgreSQL 7.3$B0J9_%m%1!<%k%5%]!<%H$,I,$:M-8z$K$J$C$F$$$^$9$,!$(B - $B$3$l$OF|K\8l$J$I$r;HMQ$9$k:]$K$O2?$N%a%C%j%H$b$J$$$P$+$j$G$J$/!$>c32(B - $B$N860x$K$J$C$?$j!$(BLIKE$B8!:w$d@55,I=8=8!:w$G%$%s%G%C%/%9$,M-8z$K$J$i$J(B - $B$$$J$I$NLdBj$r0z$-5/$3$9$N$G!$L58z$K$7$F$*$/$3$H$r$*$9$9$a$7$^$9!%%m(B - $B%1!<%k%5%]!<%H$rL58z$K$9$k$?$a$K$O!$(B - - --no-locale - - $B%*%W%7%g%s$r;XDj$7$^$9!%(B - - createdb $B$G$O0J2<$N%*%W%7%g%s$G%(%s%3!<%G%#%s%0$,;XDj$G$-$^$9!%(B - - -E $B%(%s%3!<%G%#%s%0(B - --encoding=$B%(%s%3!<%G%#%s%0(B - - create database $B$G$O0J2<$N%*%W%7%g%s$G%(%s%3!<%G%#%s%0$,;XDj$G$-$^$9!%(B - - CREATE DATABASE dbanme WITH ENCODING = '$B%(%s%3!<%G%#%s%0(B';
