#!/bin/sh # postgresql This is the init script for starting up the PostgreSQL # server # # chkconfig: - 64 36 # 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 # use functions, add conditional restart # Version 7.0.3 Lamar Owen # 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 # initdb parameters have changed. # Version 7.1.2 Trond Eivind Glomsrd # 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 # sync up. # Karl's fixes for some quoting issues. # Version 7.2b2 Lamar Owen # version change. # Version 7.2 final. Lamar Owen # 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 # Multiple postmasters, courtesy Karl DeBisschop # Version 7.4 Lamar Owen. # Version 7.4.3 Tom Lane # Support condstop for uninstall # Minor other changes suggested by Fernando Nasser. # Version 7.4.5 Tom Lane # 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. # PGVERSION is: PGVERSION=7.4 # Source function library.
