I just noticed that this patch broke the case where a standalone backend
is sent a query that throws an error -- instead, we get a segmentation
fault.  Example:

echo "foobar" | postgres --single
PostgreSQL stand-alone backend 9.5devel
backend> Segmentation fault

I guess we could have a src/test/modules subdir that tests simple stuff
on standalone backends ...

Ugh, sorry.  Fixed.

Wouldn't hurt.  Although it's not something that's likely to get
broken very often.
