Hi,
Attached is a patch that replaces the lc_messages with lc_time when
using to_char in translation mode (TM) [1]. It doesn't change the output
behaviour. Per discussion [2], it's using some cache mechanism so we
don't need to call setlocale() all the time.
Some issues:
(i) some locales don't capitalize the first letter. I'm using
pg_toupper() to do the job but I'm afraid it's not appropriated. I'm
using it 'cause i'm too lazy to move localized_str_toupper(). Any
suggestions?
(ii) it didn't address the problem spotted at [3][4]. IMHO, it's ok for
a non-superuser to set lc_time. Opinions?
