Make me right if I mistake. When we was developing operator @@, I saw that postgres don't use index in select if operation has not commutator. But operator with different types in argument can't be commutator with itself. So I maked operator ~~ only for postgres can use index access for operator @@. There is no any difficulties to adding index support for operator ~~. The same things is with contrib/tsearch module. But I think that there is not any other necessity in presence ~~. -- Teodor Sigaev [EMAIL PROTECTED] ---------------------------(end of broadcast)--------------------------- TIP 5: Have you checked our extensive FAQ? http://www.postgresql.org/users-lounge/docs/faq.html
