Description:
I believe that the documented behavior of EXCEPT is not in agreement
with Postgres behavior (I'm using Postgres 9.5). The documents say:

WaitForBackgroundWorkerShutdown() was added in 924bcf4f16d, but never
documented which seems like an oversight for such a useful function. The
attached patch adds this to bgworker.sgml, and also fixes what I believe are
typos in the WaitForBackgroundWorkerStartup paragraph.
