Re: Operator is not unique

Doing a inner join with pg_proc I´ll get this result. So, none of this casts
I´ve created. Column prorettype is different, this is the problem ?select
format_type(castsource, NULL), format_type(casttarget, NULL),castfunc,
castcontext, castmethod, pr.* from pg_cast inner join pg_proc pr on castfunc
= pr.oid where (castsource = 'numeric'::regtype or castsource =
'bigint'::regtype) and format_type(casttarget, NULL) in ('numeric','bigint')
order by castsource;
format_type format_type castfunc castcontext castmethod proname pronamespace
proowner prolang procost prorows provariadic protransform prokind prosecdef
proleakproof proisstrict proretset provolatile proparallel pronargs
