Hi all,

Attaching latest pg_background patch for review as per design proposed
on 22 Dec '16 with following minor changes in the api.

Changes:
1. pg_background_launch renamed to pg_background_start
2. pg_background_detach renamed to pg_background_close
3. Added new api to display previously launch background worker & its
result count waiting to be read.

Todo:
1. Documentation.

Thanks to Andrew Borodin & David Fetter for regression test script,
added in the attached version patch.

Note that attached patches need to apply to the top of the Peter
Eisentraut's v2 patch[1].
Patch 0001 is does some changes in BackgroundSession code required by
pg_background, which we are currently discussing on BackgroundSession
thread.
