Function MakeCollatedType

pkg/sql/types/types.go:1000–1008

MakeCollatedType is like MakeCollatedString but also handles NULL and arrays of string types that need to become arrays of collated string types. UNKNOWN => STRING COLLATE EN []STRING => []STRING COLLATE EN

(typ *T, locale string)

// UNKNOWN  => STRING COLLATE EN
// []STRING => []STRING COLLATE EN
func MakeCollatedType(typ *T, locale string) *T {
	if typ.Family() == ArrayFamily {
		return MakeArray(MakeCollatedType(typ.ArrayContents(), locale))
	}
	if typ.Family() == UnknownFamily {
		return MakeCollatedType(String, locale)
	}
	return MakeCollatedString(typ, locale)
}

// MakeDecimal constructs a new instance of a DECIMAL type (oid = T_numeric)
// that has at most "precision" # of decimal digits (0 = unspecified number of
