Installing a PostgreSQL Server under NetBSD is pretty easy. The recommended way is to install the prebuilt postgresql binaries. The PostgreSQL Server depends on the postgreSQL Client.

#   Setting PKG_PATH 

Setting PKG_PATH enables us to easily download and install packages and it's dependencies. 
    
    # export PKG_PATH=https://cdn.netbsd.org/pub/pkgsrc/packages/NetBSD/$(uname -m)/$(uname -r)/All/ 
    

or if you are using csh: 
    
    # setenv PKG_PATH https://cdn.netbsd.org/pub/pkgsrc/packages/NetBSD/$(uname -m)/$(uname -r)/All/ 
    

You should keep this in your .profile, .bash_profile, if you mainly using binaries. 

#   Installing the PostgreSQL Server 
    
    # pkg_add -v postgresql92-server
    

This will install the postgresql client and the server and any missing dependency (readline, perl) and will add the user **pgsql** to your user database. 

That's it. Almost. 

#   Configuring the Server 

Please copy the pgsql example script to /etc/rc.d/ 
    
    # cp /usr/pkg/share/examples/rc.d/pgsql /etc/rc.d
    

If you want to keep the database cluster other place than the default location, just change the user **pgsql'**s home directory, before proceeding to the initialisation: 
    
    # usermod -d /var/db/pgsql pgsql
    

This directory must be owned by pgsql:pgsql. 

and then 

#   Starting the Server 

If you want to initialise the database with a local other than "C", for example with unicode, invoke this before starting postgresql for the first time: 
    
    # /etc/rc.d/pgsql initdb -E unicode
    

please start the server entering: 
    
    # /etc/rc.d/pgsql start
    

This will create all necessary initial databases on the first start. 

#   Start on every boot 

To start the server on every boot add 
    
    pgsql=yes
    

to your /etc/rc.conf 

#   Creating an example Database 

To create a database switch to the user pgsql 
    
    # createdb -e -h 127.0.0.1 -U pgsql newdbname
    

and create the database 
    
    $ createdb testdb
    $ exit
    

#   Using the Database 

Postgres provides a Tool to manage the Database called **psql**. 
    
    
    # psql -U pgsql testdb
    Welcome to psql 8.0.4, the PostgreSQL interactive terminal.
    
    Type:  \copyright for distribution terms
           \h for help with SQL commands
           \? for help with psql commands
           \g or terminate with semicolon to execute query
           \q to quit
    
    testdb=#
    

#   PHP and PostgreSQL 

You may wish to install the postgres Module for PHP, e.g. for PHP 7.0 use:
    
    # pkg_add -v php70-pgsql
    

Have fun.
