Hi all,I have been having trouble with my django development project finding the postgresql database. In the process of looking for the source of the problem I found that there are versions of postgresql installed for 9.1 through 9.6 . Are all of these copies necessary and can I safely remove all of the ones that I am not using for my project or are there other packages on the system that are using those.
