Since triggers take no parameters, I'm not sure this is wrong. But if
it is wrong, then the code at fault is ExecCallTriggerFunc, not
FunctionCallInvoke. FunctionCallInvoke is just for *invoking*, not
for deciding whether to invoke.

Ugh. The performance cost would be excessive. Instead, when fmgr is
setting up to call a setuid function, have it insert an extra level of
function handler that does the save/setup/restore of current UID.
That way, the cost is zero when you're not using the feature (which is
nearly always).
