Fix t_isspace(), etc., when datlocprovider=i and datctype=C.
Check whether the datctype is C to determine whether t_isspace() andrelated functions use isspace() or iswspace().Previously, t_isspace() checked whether the database default collationwas C; which is incorrect when the default collation uses the ICUprovider.Discussion:https://postgr.es/m/79e4354d9eccfdb00483146a6b9f6295202e7890.camel@j-davis.comReviewed-by: Peter EisentrautBackpatch-through: 15
