PostgreSQL: Fuzzy search with levenshtein()

Ever wanted to implement a “Did you mean?” feature in your search results? Google is said to have greatly increased its user engagement with it. Here is how to implement it simply in Postgres (v9.1+):

Install the extension:

CREATE EXTENSION fuzzystrmatch;

// Here is btree.inl, which is the thing you would write yourself.

// Unlike C++ templates, the granularity of these lightweight templates is at the
// module level rather than the function or class level. You can think of it like
// ML functors (parameterized modules) except that there isn't any static checking
// of signatures (in that respect, it's like C++ templates). In my view, this style
// of parameterized generative modules is generally the better conceptual framework.

// This is a completely valid C file even prior to preprocessing, so during library
// development you can just include this file directly. That is a big win for testing

# template.py btree.inl => btree.h, btree.out.inl

import re
import sys
import os
import os.path

if len(sys.argv) != 2:
    print "Usage: template.py <filename>"
    sys.exit(1)

LIBRARY WRITING REFERENCE LIST
===============================
1.) Designing and Evaluating Reusable Components (Casey Muratori: http://mollyrocket.com/casey/stream_0028.html)
----------------------------------------------------------------------------------------------------------------
_THE_ reference on API design up to this day on the internet. Nobody should write a library without having seen this.
I come back to this talk every N number of weeks it is that good.

2.) stb_howto (Sean Barrett: https://github.com/nothings/stb/blob/master/docs/stb_howto.txt)
--------------------------------------------------------------------------------------------
Sean Barretts single header libraries (https://github.com/nothings/stb) was the first time for me that I came across

/* Lightweight module based templates in standard C
===================================================
This is a proof of concept example of lightweight module based templates in C and
is loosely based on https://gist.github.com/pervognsen/c56d4ddce94fbef3c80e228b39efc028 from Per Vognsen.
While his approach (at least as far as I understood) is based on a python script to generate
the .h/.c files for you is this implementation contained in one single header file.

This is an outline to show how you can use the single header approach
and bend it to its absolute extrems. I tend to write specialized datastructures
for most of my problems but sometimes it happens that I have to use a particular

API Design: Coroutines APIs (Janurary-2017)

I am currently dealing with a lot of libraries at work. Both third party as well as libraries written or being currently in process of being written by me. I absolutely love writing and working with libraries. Especially if they present or bring me to either a new or different approach to solve a problem. Or at least provide a different view.

Over time I noticed however that quite regulary we had to decide that we cannot use a third party library. Often it is the usual reason.
