I think this particular example would be a mistake, because that cast would be lossy, so you want to invoke it only when the user explicitely selects it. The other way around would be fine, I think, that is, F(float) F(float8) and the call is F(int) > PS This patch needet, because in any case we must calc prefer more > smartly, yes this patch is 1/10 of full solution, but it`s first step!!! Well, if the other 9/10 were clear, there would be no discussion. The problem is that the missing bits have not been designed and thus we don't know if this 1/10 will be useful to them. We need to find a complete design before committing to any initial portion which may turn out to be bogus down the road. -- Álvaro Herrera <alvhe...@commandprompt.com> The PostgreSQL Company - Command Prompt, Inc.
