# 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.
# Version 7.3 Lamar Owen <lamar.owen@ramifordistat.net>
# Multiple postmasters, courtesy Karl DeBisschop
# Version 7.4 Lamar Owen.
# Version 7.4.3 Tom Lane <tgl@sss.pgh.pa.us>
# Support condstop for uninstall
# Minor other changes suggested by Fernando Nasser.
# Version 7.4.5 Tom Lane <tgl@sss.pgh.pa.us>
# Rewrite to start postmaster directly, rather than via pg_ctl; this avoids
# fooling the postmaster's stale-lockfile check by having too many
# postgres-owned processes laying about.

# Note: the specfile ordinarily updates this during install
