Description

HAWQ-271 (Remove external python modules) removed a lot of external python modules besides pygresql. Now to install pygresql, we have to hack a bit as https://cwiki.apache.org/confluence/display/HAWQ/Build+and+Install said, i.e. install postgresql package at first and then remove it after installing pygresql, else pip will report error like "pg_config: command not found". Since installing postgresql is a bit painful and the workaround seems to be ugly, we could revert the code change for pygresql for HAWQ-271. That is to say, users do not need to install pygresql themselves. Note that we did some hack to upstream pygresql.
