PhpPgAdmin ERROR: column “spclocation” does not exist

The Installation of PostgreSQL and phpPgAdmin was great with the following;
phpPgAdmin 5.0.4-1.el6
Centos 6.3
PostgreSQL 9.4.1

Attempt to create a new database using phpPgAdmin, the following error appears
ERROR: column “spclocation” does not exist

Possible cause;
Using outdated phpPgAdmin
There is no definition of the column spclocation for PostgreSQL version 9.4.


Step 1: Edit Connection.php

In Centos Linux, go to the folder /usr/share/phpPgAdmin/classes/database/ and notice that there are no Postgresql file for 9.4. Edit the file Connection.php. Add the case '9.4' line around line number 82, as shown below;

// Detect version and choose appropriate database driver
                switch (substr($version,0,3)) {
                        case '9.4': return 'Postgres94'; break;
                        case '8.4': return 'Postgres'; break;

Step 2: Edit files

Make a copy Postgres84.php file with the command below;
#cp Postgres84.php Postgres94.php

Open Postgres.php and copy the functions getTablespaces and getTablespace to the file Postgres94.php

Edit Postgres94.php;

Replace all references of version from 8.4 to 9.4. E.g.

Amend the 2 lines
$sql = "SELECT spcname, pg_catalog.pg_get_userbyid(spcowner) AS spcowner, spclocation,
$sql = "SELECT spcname, pg_catalog.pg_get_userbyid(spcowner) AS spcowner, pg_tablespace_location(oid) as spclocation,


$sql = "SELECT spcname, pg_catalog.pg_get_userbyid(spcowner) AS spcowner, spclocation,
$sql = "SELECT spcname, pg_catalog.pg_get_userbyid(spcowner) AS spcowner, pg_tablespace_location(oid) as spclocation,

Step 3: Create database

Open the web browser and access phpPgAdmin to create a new database.

Installation of Postgresql and phpPgAdmin

PostgreSQL is an object-relational database management system and can be downloaded from or via Linux packagers like Yum or through other 3rd party solutions. PgAdmin3 can be installed to manage the database.

It is available under PostgreSQL License, similar to the MIT license.

Today, a large number of PHP programming framework have support to use PostgreSQL.

PhpPgAdmin is a web based administration tool for PostgreSQL. Source and binary can be downloaded from

It is available under GNU General Public License.

Steps listed if for installation environment:
Centos 6.3
Selinux in permissive mode
Apache httpd version 2.2.15

Step 1:  Install PostgreSQL

Refer previous posting for the installation. PostgreSQL version 9.4 is available at this point and its safe to say that just replacing 9.3 with 9.4 will work. Here are list of the changes;

Yum repository

  • 32bits:
  • 64bits:

RPM packages: postgresql94-server postgresql94-contrib

Ensure TCPIP connection is setup, edit /var/lib/pgsql/9.4/data/postgresql.conf
listen_addresses = '*'
port = 5432

Important files:
Configure authentications: /var/lib/pgsql/9.4/data/pg_hba.conf
Configure server to accept TCPIP: /var/lib/pgsql/9.4/data/postgresql.conf

Starting and enabling at Linux bootup.
service postgresql-9.4 start
chkconfig postgresql-9.4 on

Step 2: Configure firewall

Its good to keep local firewall enabled. Edit at end of /etc/sysconfig/iptables

-A INPUT -m state --state NEW -m tcp -p tcp --dport 5432 -j ACCEPT
-A INPUT -m state --state NEW -m tcp -p tcp --dport 80 -j ACCEPT

Restart iptables.

Note: Although the Linux is in permissive, its good to enable web servers to access the database using the command;
setsebool -P httpd_can_network_connect_db 1

Step 3: Install phpPgAdmin

From the command line, type
yum install epel-release
yum install phpPgAdmin

Edit /etc/httpd/conf.d/phpPgAdmin.conf

Alias /phpPgAdmin /usr/share/phpPgAdmin

        # Apache 2.2
        Order deny,allow
        Allow from all

Then restart httpd.

Step 4: Configure phpPgAdmin

Lets use a server administration configuration called "Test Server" that we can practice with. Edit and/or add following server instance to /etc/phpPgAdmin/
        $conf['servers'][1]['desc'] = 'Test Server';
        $conf['servers'][1]['host'] = 'localhost';
        $conf['servers'][1]['port'] = 5432;
        $conf['servers'][1]['sslmode'] = 'allow';
        $conf['servers'][1]['defaultdb'] = 'postgres';
        $conf['servers'][1]['pg_dump_path'] = '/usr/bin/pg_dump';
        $conf['servers'][1]['pg_dumpall_path'] = '/usr/bin/pg_dumpall';

        $conf['extra_login_security'] = false;
        $conf['owned_only'] = true;

Restart PostgreSQL.

Open a web browser and type in the URL http://localhost/phpPgAdmin

Some important files that might be of use;

  • /usr/share/phpPgAdmin/conf/
  • /etc/httpd/conf.d/phpPgAdmin.conf
  • /etc/phpPgAdmin/

  1. phpPgAdmin: If keep getting "Login failed", check the PostgreSQL server for problems. Most likely the pg_hba.conf isnt fully using md5.
  2. References on administration from PostgreSQL Documentation.
