PostgreSQL, also referred to as Postgres, is a database management application that is used by many of the top operating systems including Solaris, OSX, Windows and Linux. Its history dates back to 1982 when it was once known as the Ingres project. This open-source software controls your PostgreSQL databases in your cPanel web hosting and cPanel VPS hosting accounts.
To fully manage PostgreSQL databases within your web hosting account, there is an application called phpPgAdmin, this easy to use program is much like its MySQL counterpart called PHPMyAdmin. You can also connect to the PostgreSQL using a standard pg_Connect() function for connectivity directly within PHP.
If you have any questions, or need any assistance, please feel free to reach out to your cPanel web hosting support team and they will be glad to answer any PostgreSQL questions you may have.
