Hmm that's very good point. I did see these missing coverage issue when 
running tests that explicitly start more instances of postgres before 
though. And with some quick googling, parallel testing seems to be issue 
with gcov for more people.

I wonder if the program checksum that gcov calculates when merging the 
.gcda data while updating it is somehow different for separately started 
instances but not for the ones forked from same parent or something. I 
don't know internals of gcov well enough to say how exactly that works.
