Patch for NOTICE messages to PQfn() from backend

If PQfn() receives NOTICEs from the backend, it fails because there is no
provision to deal with them.

This patch (supplied by Anders Hammarquist <iko@netg.se> to me as Debian
maintainer of postgresql) cures the problem:

Come to me, all you who labour and are heavily laden, and I will
give you rest. Take my yoke upon you, and learn from me; for I am
meek and lowly in heart, and you shall find rest for your souls.
For my yoke is easy and my burden is light. (Matthew 11: 28-30)
