hosting product, on both shared and dedicated machines. We currently offer Oracle and MySQL, and it would be a nice middle-ground. However, as shipped, PostgreSQL lacks the following features we need that MySQL has: 1. The ability to listen only on a particular IP address. Each hosting customer has their own IP address, on which all of their servers (http, ftp, real media, etc.) run. 2. The ability to place the Unix-domain socket in a mode 700 directory. This allows us to automatically create an empty database, with an empty DBA password, for new or upgrading customers without having to interactively set a DBA password and communicate it to (or from) the customer. This in turn cuts down our install and upgrade times. 3. The ability to connect to the Unix-domain socket from within a change-rooted environment. We run CGI programs chrooted to the user's home directory, which is another reason why we need to be able to specify where the Unix-domain socket is, instead of /tmp. 4. The ability to, if run as root, open a pid file in /var/run as root, and then setuid to the desired user. (mysqld -u can almost do this; I had to patch it, too). The patch below fixes problem 1-3. I plan to address #4, also, but haven't done so yet. These diffs are big enough that they should give the PG development team something to think about in the meantime :-) Also, I'm about to leave for 2 weeks' vacation, so I thought I'd get out what I have, which works (for the problems it tackles), now. With these changes, we can set up and run PostgreSQL with scripts the same way we can with apache or proftpd or mysql. In summary, this patch makes the following enhancements: 1. Adds an environment variable PGUNIXSOCKET, analogous to MYSQL_UNIX_PORT, and command line options -k --unix-socket to the relevant programs. 2. Adds a -h option to postmaster to set the hostname or IP address to listen on instead of the default INADDR_ANY. 3. Extends some library interfaces to support the above. 4. Fixes a few memory leaks in PQconnectdb(). The default behavior is unchanged from stock 7.0.2; if you don't use any of these new features, they don't change the operation. David J. MacKenzie |

Pavel Behal Revised by: Tatsuo Ishii Email: behal@opf.slu.cz Licence: The Same as PostgreSQL Sorry for my Eglish and C code, I'm not native :-) !!!!!!!!!!!!!!!!!!!!!!!!! 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) [PostgreSQL 6.5.1$B$G$O$3$N%9%F%C%W$OI,MW$"$j$^$;$s!#(B-- $B@P0f(B] 2) Compile with enabled locale and multibyte set to LATIN2 3) Setup properly your instalation, do not forget to create locale variables in your profile (environment). Ex. (may not be exactly true): LC_ALL=cs_CZ.ISO8859-2 LC_COLLATE=cs_CZ.ISO8859-2 LC_CTYPE=cs_CZ.ISO8859-2 LC_MONETARY=cs_CZ.ISO8859-2 LC_NUMERIC=cs_CZ.ISO8859-2 LC_TIME=cs_CZ.ISO8859-2 4) You have to start the postmaster with locales set! 5) Try it with Czech language, it have to sort 5) Install ODBC driver for PgSQL into your M$ 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 ------------------------------------------------------------------- $B;29M(B2$B!'(BSJIS$B%f!<%6Dj5AJ8;z(B (UDC) $B$r$I$&07$&$+$H8@$&$3$H$K$D$$$FCf>r$5$s(B (nak@email.com)$B$+$i$$$?$@$$$?LdBjDs5/$H2r@b$G$9!#(B -------------------------- $B0zMQ3+;O(B ---------------------------------- --- 1.
