How to delete PGCLI

PGC is a package and update manager, similar to yum or apt-get, specifically for PostgreSQL and related community projects. PGC enables you to easily find and install packages, configure multiple versions of PostgreSQL, update existing applications, and control services (like Postgres or PostgreSQL Studio) by starting and stopping from the command line.
For example to install PostgreSQL server version 9.6 you type pgc install pg96.
For more information on the different command options type pgc help or visit the official documentation.
