I've also thought a similar implementation but there seems
a problem of efficiency.
As far as I see wcsftime() is almost = strftime() + mbstowcs() and so using strftime() is effective at least for the
following
cases.
1) LC_CTIME is "C".
2) LC_CTYPE != C and the database encoding != UTF-8. In this case the current restriction of PostgreSQL requires that
the database encoding matches the encoding of the LC_CTYPE.
We seem to be able to call strftime() directly in above cases.
Comments ?
