Functions within PostgreSQL can be setup to return rows and included in queries just like any other table. Continuing with our theme of trying to push Elixir and Phoenix a little on this site rebuild, we will move our site search inside of a database function and experiment with different ways to call it from Ecto.
I'm at the borderline of obsessed with Elixir and Phoenix lately. I've avoided writing about it so far because it feels a bit too good to be true. In an effort to test my own enthusiam, I decided to rebuild this site with them in the most ridiculous way possible just to try to test some limits. Because I already have an unhealthy obsession with PostgreSQL, we're getting crazy with it too.

PostgreSQL has a great feature called Foreign Data Wrappers (FDW) that allows it to connect directly to outside systems. Although the setup can be a little complicated, once it’s available you can run queries with joins or subqueries against them, insert data, create views, etc. Heroku has dramatically simplified the process of using FDW with PostgreSQL and Redis thanks to Data Links. Let’s try it out.
Backing up your data is one of the most critical activities for your application. Heroku PGBackups makes the entire experience pretty simple but comes with a lot of flexibility too, with a number of options for smooth restoration.
PostgreSQL is becoming the relational database of choice for web development for a whole host of good reasons. That means that development teams have to make a decision on whether to host their own or use a database as a service provider. The two biggest players in the world of PostgreSQL are Heroku PostgreSQL and Amazon RDS for PostgreSQL. Here's a detailed comparison.
In August I taught a course titled Ruby on Rails and PostgreSQL - Intro to Advanced in Greenville over the span of 3 weeks. Here is the compilation of slides from the class.
Here's the video from the August UpstatePHP meeting in Greenville discussing SQL vs NoSQL and where they are useful for your development process. I represented SQL solutions (*cough* PostgreSQL *cough*) while Benjamin Young represented NoSQL. Ben has actively contributed to CouchDB, worked for Cloudant, Couchbase, organizes the REST Fest Unconference (happening again September 25-27th) and is the owner of Big Blue Hat. I am a gainfully employed programmer...so...there's that.
If you've spent any amount of time on this site you may have noticed that I'm fond of PostgreSQL...and Ruby on Rails...and that I dislike the general trend among Rails developers to ignore all of the amazing features in PostgreSQL that make your application better in favor of risking data integrity just so that all logic can remain in Rails. So here's my top collection of Rails gems to get at all that untapped power in PostgreSQL that you didn't know you had.
Nearly a year ago I put together an hour long presentation on PostgreSQL to provide an overview of all of the benefits it provides you over other options in the database space. In hindsight, that wasn't nearly enough time because it has the capability to replace almost your entire application stack outside of the web server. In any case, here is an attempt to summarize all of the amazing functionality that you're cheating yourself out of by not choosing PostgreSQL.
Beginning August 18th I will be offering a three week evening class aimed at professional programmers who want to learn Ruby on Rails and PostgreSQL, with the goal of becoming proficient with both in a very short time.
An overview of Ruby, jRuby, Rails, Torquebox, and PostgreSQL that was presented as a 3 hour class to other programmers at The Ironyard in Greenville, SC in July of 2013. The Rails specific sections are mostly code samples that were explained during the session so the real focus of the slides is Ruby, "the rails way" / workflow / differentiators and PostgreSQL.
This is a presentation I recently gave to provide an overview of PostgreSQL and some of it's excellent features, including full-text search, multiple built in datatypes, data compression and extensions.
Also, Morgan Freeman is narrating. You're welcome.
