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.
First let's check something.
brew info postgresqlThe top of what gets printed as a result is the most important:
| package main | |
| import ( | |
| "github.com/guelfey/go.dbus" | |
| "log" | |
| "bufio" | |
| "os" | |
| ) | |
| func main() { |
| [0-9a-zA-Z]{2} | |
| 30-39,41-5a,61-7a | |
| a:61 z:7a A:41 Z:5a 0:30 9:39 | |

G-WAN is a new free web server. They seem to be very proud of it, or at least just want to make a lot of money. Well anyway, in almost every sentence they write, they claim that they are 20% cooler than anything else. It feels a bit arrogant. I have to admit, I don't know a lot about web servers, so I can't speak to how good they are.
However, then I saw their Captcha example. I also don't know much about machine learning algorithms, OCR, and stuff like that, but I do know how to read pixels. I also know how to compare values with python :P
They say the following about their Captcha:
| #!/bin/sh | |
| # | |
| # Runs during git flow release start | |
| # | |
| # Positional arguments: | |
| # $1 Version | |
| # | |
| # Return VERSION - When VERSION is returned empty gitflow | |
| # will stop as the version is necessary | |
