You can try FunctionCall5Coll() or OidFunctionCall5Coll() functions.
OidFunctionCall5Coll() calls fmgr_info() and FunctionCall5Coll(). What
you only need is Oid of the target function.
FunctionCall5Coll() can be useful and used when you have a cache
variable of the function, where you store previously calculated
FmgrInfo.
