+# postgresql	This is the init script for starting up the PostgreSQL
+#		server
+#
+# chkconfig: - 85 15
+# description: Starts and stops the PostgreSQL backend daemon that handles \
+#	       all database requests.
+# processname: postmaster
+# pidfile: /var/run/postmaster.pid
+
+# Version 6.5.3-2 Lamar Owen
+# Added code to determine if PGDATA exists, whether it is current version
+#     or not, and initdb if no PGDATA (initdb will not overwrite a database).
+
+# Version 7.0 Lamar Owen
+# Added logging code
+# Changed PGDATA.
+#
+
+# Version 7.0.2 Trond Eivind Glomsrd <teg@redhat.com>
+# use functions, add conditional restart
+          
+# Version 7.0.3 Lamar Owen <lamar@postgresql.org>
+# Check for the existence of functions before blindly using them 
+# in particular -- check for success () and failure () before using.
+# More Cross-distribution support -- PGVERSION variable, and docdir checks.
+
+# Version 7.1 Release Candidate Lamar Owen <lamar@postgresql.org>
+# initdb parameters have changed.
+
+# Version 7.1.2 Trond Eivind Glomsrd <teg@redhat.com>
+# Specify shell for su
+# Handle stop better - kill unwanted output, make it wait until the database is ready
+# Handle locales slightly differently - always using "C" isn't a valid option 
+# Kill output from database initialization 
+# Mark messages for translation
+
+# Version 7.1.2-2.PGDG Lamar Owen <lamar.owen@wgcr.org>
+# sync up.
+# Karl's fixes for some quoting issues.
+
+# Version 7.2b2 Lamar Owen <lamar.owen@wgcr.org>
+# version change.
+
+# Version 7.2 final.  Lamar Owen <lamar.owen@wgcr.org>
+# reload from Peter E.
+# Eliminate the pidof postmaster test in stop -- we're using pg_ctl so we don't need pidof.
+# Tested the $? return for the stop script -- it does in fact propagate.
+# TODO: multiple postmasters.
