> it means, so we must not implement any new operator? No, it doesn't mean any such thing. If we invented, say, "int4 => int4" it would not break someone's use of => for their own custom datatype. What you're proposing would be a global redefinition of the meaning of =>. This is closer to creating a new reserved word, which as I'm sure you know we try hard to avoid, even for keywords that the spec says we can reserve. The bar for making a new fully-reserved word that isn't in the spec is *very* high. regards, tom lane -- Sent via pgsql-hackers mailing list (pgsql-hackers@postgresql.org) To make changes to your subscription: http://www.postgresql.org/mailpref/pgsql-hackers
