Robert Haas b8a439b650 Allow notifications to bgworkers without database connections.
Previously, if one background worker registered another background
worker and set bgw_notify_pid while for the second background worker,
it would not receive notifications from the postmaster unless, at the
time the "parent" was registered, BGWORKER_BACKEND_DATABASE_CONNECTION
was set.

To fix, instead instead of including only those background workers that
requested database connections in the postmater's BackendList, include
them all.  There doesn't seem to be any reason not do this, and indeed
it removes a significant amount of duplicated code.  The other option
is to make PostmasterMarkPIDForWorkerNotify look at BackgroundWorkerList
in addition to BackendList, but that adds more code duplication instead
of getting rid of it.

Patch by me.  Review and testing by Ashutosh Bapat.

PostgreSQL Database Management System
=====================================

This directory contains the source code distribution of the PostgreSQL
database management system.

PostgreSQL is an advanced object-relational database management system
that supports an extended subset of the SQL standard, including
transactions, foreign keys, subqueries, triggers, user-defined types
and functions.  This distribution also contains C language bindings.

PostgreSQL has many language interfaces, many of which are listed here:

See the file INSTALL for instructions on how to build and install
PostgreSQL.  That file also lists supported operating systems and
hardware platforms and contains information regarding any other
software packages that are required to build or run the PostgreSQL
system.  Copyright and license information can be found in the
file COPYRIGHT.  A comprehensive documentation set is included in this
distribution; it can be read as described in the installation
instructions.

The latest version of this software may be obtained at
http://www.postgresql.org/download/.  For more information look at our
web site located at http://www.postgresql.org/.
