Обсуждение: postgresql "init script" for postgres 9.2.15
Hi, I've been searching for a 9.2.15 version of the postgresql script for "init script for starting up the PostgreSQL". I have managed to find older versions than what we are currently using, 8.2.5 but haven't had any luck finding a new version in the postgres 9.2.15 rpms. We are moving from CentOS 5 to CentOS 7 and need to update postgres from 8.2.5 to 9.2.15.
Below is the version I have. Where can I find a version of this script for 9.2.15? Thank you.

# processname: postmaster
# pidfile: $TV_HOME/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>

# Eliminate the pidof postmaster test in stop -- we're using pg_ctl so we don't need pidof.

# 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

Thank you but in our appliance, we are not running postgres as a service, we are running it programatically with this script, call postmaster to start it for instance instead of using the service framework. Is there an equivalent in 9.x or does it now have to run as a service. I was able to modify the script to get 9.2 to run but I was hoping this script had been updated for 9.x. The current script uses --auth='ident sameuser' when calling initdb for instance which is not supported in 9.2.

Please don't top-post.
Thank you but in our appliance, we are not running postgres as a service, we are running it programatically with this script, call postmaster to start it for instance instead of using the service framework. Is there an equivalent in 9.x or does it now have to run as a service.
It is not surprising that a piece of code no longer required by the package for its main operation has not been maintained (maybe it has, I'm not familiar with the Centos assets).
PostgreSQL is capable of being launched in any number of ways. But as you move toward minority status (which initd on Centos 7 seems to be) the wealth of third-party maintained stuff to pick from tends to decrease.

You could try looking in the Fedora 15 RPMs --- that was the last
non-systemd Fedora release, I believe. It looks like Fedora was on
Postgres 9.0.x at that point, so you might still need to do a bit more
fiddling to get it to work with PG 9.2; but it'd be closer than scripts
intended for 8.2, for sure.
Keep in mind that scripts like this are distro-maintained, not maintained
by the Postgres core project; and they tend to get a LOT more churn caused
by distro-specific issues than churn caused by Postgres changes. It's
not really clear to me that you want to do anything except make whatever
changes you have to in the scripts you already have. You may spend more
time dealing with useless-to-you changes than you save by not doing your
own research on what changed in Postgres.

Well first: systemctl enable postgresql-9.4.service would make it a service that starts at boot. If you just want to start and stop on demand then: systemctl start postgresql-9.4.service systemctl stop postgresql-9.4.service If you set on using init.d/ scripts then: https://git.postgresql.org/gitweb/?p=postgresql.git;a=blob_plain;f=contrib/start-scripts/linux;hb=e9dca8ce147f32d7d64a9e64f9d8339310ad6535 > > > Steve > > steve.langlois@tavve.com > > ------------------------------------------------------------------------ > *From:* Adrian Klaver <adrian.klaver@aklaver.com> > *Sent:* Wednesday, July 13, 2016 5:11:24 PM > *To:* Steve Langlois; pgsql-general@postgresql.org > *Subject:* Re: [GENERAL] postgresql "init script" for postgres 9.2.15 > > On 07/13/2016 01:56 PM, Steve Langlois wrote: >> >> Hi, I've been searching for a 9.2.15 version of the postgresql script >> for "init script for starting up the PostgreSQL".
