"""
This utility addresses the InegrityError that occurs when you try to add a new record to 
(probably a recently ported) postgres database while using Django, here's more . . . 

duplicate key value violates unique constraint "<app>_<table>_pkey"
DETAIL:  Key (id)=(2) already exists.

The problem here is that the Postgres sequence generators are out of sync with your data. 
Here's a good overview: http://www.vlent.nl/weblog/2011/05/06/integrityerror-duplicate-key-value-violates-unique-constraint/

#Since every `git pull` is actually a merge. We can use it to automaticly run basic Django tasks after pulling from the upstream master branch (or any other)
#Notice: This won't run at git fetch. since fetch doesn't merge anything
#Installation:
#	copy this script with the name:`post-merge.sh` to your project root folder
#	symlink it to the ./git/hooks/post-merge: `ln post-merge.sh .git/hooks/post-merge
 
#You should have bash (windows users, means cygwin/mingw anything that works for you
#Based on the instructions here: https://oknesset-devel.readthedocs.org/en/latest/workflow.html#before-coding
