Method collatedStringTypeSQL

postgres/parser/types/types.go:2441–2451

collatedStringTypeSQL returns the string representation of a COLLATEDSTRING or []COLLATEDSTRING type. This is tricky in the case of an array of collated string, since brackets must precede the COLLATE identifier: STRING COLLATE EN VARCHAR(20)[] COLLATE DE

(isArray bool)

//	STRING COLLATE EN
//	VARCHAR(20)[] COLLATE DE
func (t *T) collatedStringTypeSQL(isArray bool) string {
	var buf bytes.Buffer
	buf.WriteString(t.stringTypeSQL())
	if isArray {
		buf.WriteString("[] COLLATE ")
	} else {
		buf.WriteString(" COLLATE ")
	}
	lex.EncodeLocaleName(&buf, t.Locale())
	return buf.String()
}

// stringTypeSQL returns the visible type name plus any width specifier for the
// STRING/COLLATEDSTRING type.
