It looks like that commit removed the plain return statements for a
void returning functions. I see in the code that there are return
statements that are there right after ereport(ERROR, just to keep the
compiler quiet. Here in this patch also, we have return; statements
after ereport(ERROR, for void returning functions. I'm not sure
removing them would cause some compiler warnings on some platforms
with some other compilers. If we're not sure, I'm okay to keep those
return; statements. Thoughts?
