Re: [HACKERS] polymorphic types - enforce casting to most common type automatically

Hi I am sending a proof concept. Current implementation is not suboptimal - I wrote this code for demonstration of current issues, and checking possible side effects of changes in this patch. The basic problem is strong restrictive implementation of polymorphic types - now these types doesn't all

[HACKERS] polymorphic types - enforce casting to most common type automatically

Hello now a functions with more than one polymorphic arguments are relative fragile due missing casting to most common type. Some our "functions" like "coalesce" can do it, so it is surprising for our users. our custom polymorphic function foo(anyelement, anyelement) working well for foo(10,20)
