Hi,
I tried this new feature in PostgreSQL. I found one bug.
Script UCS_to_8859.pl skips input lines which
1. code <0x80 or
2. ucs <0x100
I think second one is not good idea because some codes in ISO8859-2
have ucs <0x100 (e.g. 0xE9 - 0x00E9)
--------------------------------------------------
for any other purpose than PGLC_localeconv()'s internal save/restore of
locale settings. Fix cash.c to call PGLC_localeconv() rather than
making a direct call to localeconv() --- the old way, if PGLC_localeconv()
had already cached a locale result, it would be overwritten by the first
cash_in or cash_out operation, leading to wrong-locale results later.
Probably no demonstrable bug today, since we only appear to be looking
at the LC_MONETARY results which should be the same anyway, but definitely
a gotcha waiting to strike.
re-adopt these settings at every postmaster or standalone-backend startup.
This should fix problems with indexes becoming corrupt due to failure to
provide consistent locale environment for postmaster at all times. Also,
refuse to start up a non-locale-enabled compilation in a database originally
initdb'd with a non-C locale. Suppress LIKE index optimization if locale
is not "C" or "POSIX" (are there any other locales where it's safe?).
Issue NOTICE during initdb if selected locale disables LIKE optimization.
it fixing Y,YY,YYY,YYYY conversion, the docs and regress tests update
are included too.
During the patch testing I found small bug in miscadmin.h in
convertstr() declaration. Here it's fixed too.
Thanks

Makes sense. Here's a new patch, now the output even looks better:
