That's good point. You can use C/POSIX locale with LATIN1 or any other
encoding, but in such case you lost some (probably useful) text
functionalities, which are provided by specific locale (upper, lower,
and initcap functions bahaviour, sort order using ORDER BY etc.).
"For C or POSIX locale, any character set is allowed, but for other
locales there is only one character set that will work correctly. (On
Windows, however, UTF-8 encoding can be used with any locale.)"
"If you want the system to behave as if it had no locale support, use
the special locale C or POSIX."
"The drawback of using locales other than C or POSIX in PostgreSQL is
its performance impact. It slows character handling and prevents
ordinary indexes from being used by LIKE. For this reason use locales
only if you actually need them."
