How to Install PostgreSQL 10 Using Source Code in Linux

PostgreSQL also called Postgres is a powerful and open source object-relational database system. It is an enterprise level database having features such as write ahead logging for fault tolerance, asynchronous replication, Multi-Version Concurrency Control (MVCC),online/hot backups, point in time recovery, query planner/optimizer, tablespaces, nested transactions (savepoints) etc.

Postgres has its latest version 10 released on 5th Oct 2017 by postgres global development group.

PostgreSQL Features

Features of New version are as follows:

  • Logical Replication: This feature enables replication of individual database objects (be it rows, tables, or selective databases) across standby servers. It provides more control over data replication. Implemented by using publisher-subscriber model.
  • Quorum Commit for Synchronous Replication: In this feature, dba can now specify the number of standby’s that acknowledge that the changes to database has done, so that data can be considered safely written.
  • SCRAM-SHA-256 authentication: Improved security that existing MD5-based password authentication and storage.
  • Improved parallel query execution.
  • Declarative table partitioning.
  • Full text search support for JSON and JSONB.

In this article, we will explain how to install PostgreSQL 10 using source code installation in Linux systems. Those who looking for easy installation from distribution package manager they can follow these below guides.

  1. How to Install PostgreSQL 10 on CentOS/RHEL and Fedora
  2. How to Install PostgreSQL 10 on Debian and Ubuntu

Install PostgreSQL Using Source Code

As postgres is open source database, it can be built from source code according to one’s needs/requirements. we can customize the build and installation process by supplying one or more command line options for various additional features.

Major advantage of using source code installation is it can be highly customized during installation.

1. First install required prerequisites such as gcc, readline-devel and zlib-devel using package manager as shown.

# yum install gcc zlib-devel readline-devel     [On RHEL/CentOS]
# apt install gcc zlib1g-dev libreadline6-dev   [On Debian/Ubuntu]

2. Download the source code tar file from the official postgres website using the following wget command directly on system.

# wget

3. Use tar command to extract the downloaded tarball file. New directory named postgresql-10.0 will be created.

# tar -xvf postgresql-10.0.tar.bz2
# ll
Sample Output
total 19236
-rw-------. 1 root root      933 Mar 18  2015 anaconda-ks.cfg
-rw-r--r--. 1 root root     8823 Mar 18  2015 install.log
-rw-r--r--. 1 root root     3384 Mar 18  2015 install.log.syslog
drwxrwxrwx  6 1107 1107     4096 Oct  3  2017 postgresql-10.0
-rw-r--r--  1 root root 19639147 Oct  3  2017 postgresql-10.0.tar.bz2

4. Next step for installation procedure is to configure the downloaded source code by choosing the options according to your needs.

# cd postgresql-10.0

use ./configure --help to get help about various options.

Sample Output
# ./configure --help

Defaults for the options are specified in brackets.
  -h, --help              display this help and exit
      --help=short        display options specific to this package
      --help=recursive    display the short help of all the included packages
  -V, --version           display version information and exit
  -q, --quiet, --silent   do not print `checking ...' messages
      --cache-file=FILE   cache test results in FILE [disabled]
  -C, --config-cache      alias for `--cache-file=config.cache'
  -n, --no-create         do not create output files
      --srcdir=DIR        find the sources in DIR [configure dir or `..']

Installation directories:
  --prefix=PREFIX         install architecture-independent files in PREFIX
  --exec-prefix=EPREFIX   install architecture-dependent files in EPREFIX

5. Now create a directory where you want to install postgres files and use prefix option with configure.

# mkdir /opt/PostgreSQL-10/
# ./configure --prefix=/opt/PostgreSQL-10
Sample Output
checking build system type... x86_64-pc-linux-gnu
checking host system type... x86_64-pc-linux-gnu
checking which template to use... linux
checking whether NLS is wanted... no
checking for default port number... 5432
checking for block size... 8kB
checking for segment size... 1GB
checking for WAL block size... 8kB
checking for WAL segment size... 16MB
checking for gcc... gcc
checking whether the C compiler works... yes
checking for C compiler default output file name... a.out
checking for suffix of executables... 
checking whether we are cross compiling... no
checking for suffix of object files... o
checking whether we are using the GNU C compiler... yes
checking whether gcc accepts -g... yes
checking for gcc option to accept ISO C89... none needed
checking whether gcc supports -Wdeclaration-after-statement... yes
checking whether gcc supports -Wendif-labels... yes
checking whether gcc supports -Wmissing-format-attribute... yes
checking whether gcc supports -Wformat-security... yes
checking whether gcc supports -fno-strict-aliasing... yes
checking whether gcc supports -fwrapv... yes
checking whether gcc supports -fexcess-precision=standard... no

6. After configuring, next we will start to build postgreSQL using following make command.

# make

After build process finishes, now install postgresql using following command.

# make install

Postgresql 10 has been installed in /opt/PostgreSQL-10 directory.

7. Now create a postgres user and directory to be used as data directory for initializing database cluster. Owner of this data directory should be postgres user and permissions should be 700 and also set path for postgresql binaries for our ease.

# useradd postgres
# passwd postgres
# mkdir /pgdatabase/data
# chown -R postgres. /pgdatabase/data
# echo 'export PATH=$PATH:/opt/PostgreSQL-10/bin' > /etc/profile.d/

8. Now initialize database using the following command as postgres user before using any postgres commands.

# su postgres
$ initdb -D /pgdatabase/data/ -U postgres -W

Where -D is location for this database cluster or we can say it is data directory where we want to initialize database cluster, -U for database superuser name and -W for password prompt for db superuser.

For more info and options we can refer initdb –help.

9. After initializing database, start the database cluster or if you need to change port or listen address for server, edit the postgresql.conf file in data directory of database server.

Configure PostgreSQL Port
Configure PostgreSQL Port
$ pg_ctl -D /pgdatabase/data/ -l /pglog/db_logs/start.log start

10. After starting database, verify the status of postgres server process by using following commands.

$ ps -ef |grep -i postgres
$ netstat -apn |grep -i 51751
Verify PostgreSQL Database
Verify PostgreSQL Database

We can see that database cluster is running fine, and startup logs can be found at location specified with -l option while starting database cluster.

11. Now connect to database cluster and create database by using following commands.

$ psql -p 51751
postgres=# create database test;
postgres=# \l to list all databases in cluster
postgres=# \q to quit form postgres console
Connect PostgreSQL Database
Connect PostgreSQL Database

That’s It! in our upcoming articles, I will cover configuration, replication setup and installation of pgAdmin tool, till then stay tuned to Tecmint.
