I wrote a little bit about this last year: http://postgr.es/m/CA+TgmoarLfSQcLCh7jx0737SZ28qwbuy+rUWT6rSHAO=b-6...@mail.gmail.com I think it's generally a good idea, though perhaps we should consider continuing to allow '!' as a postfix operator and just removing support for any other. That would probably allow us to have a very short deprecation period, since real-world use of user-defined postfix operators seems to be nil -- and it would also make this into a change that only affects the lexer and parser, which might make it simpler. I won't lose a lot of sleep if we decide to rip out '!' as well, but I don't think that continuing to support it would cost us much. -- Robert Haas EnterpriseDB: http://www.enterprisedb.com The Enterprise PostgreSQL Company
