Details:

The "clang" static analyzer reported a number of related potential null
pointer dereferences in psql-reader.c.  I'm attaching one of the reports.

According to John Darrington:


One thing is for sure: that code could use some more comments.

The analyser is correct.  A null pointer dereference could potentially
occur if the PSQL library server started behaving oddly.  However, this
feature has some quite comprehensive tests, and there's been no problem 
so far.

I suggest that we raise a bug about this, so that I can fix it when I 
get time.
