# description: Starts and stops the PostgreSQL backend daemon that handles \

|
# 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.
