How to migrate a Homebrew-installed PostgreSQL database to a new major version (9.3 to 9.4) on OS X. See upgraded version of this guide: http://olivierlacan.com/posts/migrating-homebrew-postgres-to-a-new-version/

This guide assumes that you recently run brew upgrade postgresql and discovered to your dismay that you accidentally bumped from one major version to another: say 9.3.x to 9.4.x. Yes, that is a major version bump in PG land.

ZigZag encoding/decoding explained
ZigZag-Encoding
---------------
Maps negative values to positive values while going back and
forth (0 = 0, -1 = 1, 1 = 2, -2 = 3, 2 = 4, -3 = 5, 3 = 6 ...)
(i >> bitlength-1) ^ (i << 1)
with "i" being the number to be encoded, "^" being
XOR-operation and ">>" would be arithemtic shifting-operation
