In investigating yesterday's crash report from Hugo Osvaldo Barrera, I only looked back as far as commitf3aec2c7f5where the breakage occurred (which is why I thought the IPv4-in-IPv6 business was undocumented). But actually the logic dates back to commit3c9bb8886dand was simply broken by erroneous refactoring in the later commit. A bit of archives excavation shows that we added the whole business in response to a report that some 2003-era Linux kernels would report IPv4 connections as having IPv4-in-IPv6 addresses. The fact that we've had no complaints since 9.0 seems to be sufficient confirmation that no modern kernels do that, so let's just rip it all out rather than trying to fix it. Do this in the back branches too, thus essentially deciding that our effective behavior since 9.0 is correct. If there are any platforms on which the kernel reports IPv4-in-IPv6 addresses as such, yesterday's fix would have made for a subtle and potentially security-sensitive change in the effective meaning of IPv4 pg_hba.conf entries, which does not seem like a good thing to do in minor releases. So let's let the post-9.0 behavior stand, and change the documentation to match it. In passing, I failed to resist the temptation to wordsmith the description of pg_hba.conf IPv4 and IPv6 address entries a bit. A lot of this text hasn't been touched since we were IPv4-only.

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.
