PG Phriday: 5 Reasons Postgres Sucks! (You Won’t Believe Number 3!)

I’ve been a Postgres DBA since 2005. After all that time, I’ve come to a conclusion that I’m embarrassed I didn’t reach much earlier: Postgres is awful. This isn’t a “straw that broke the camel’s back” kind of situation; there is a litany of ridiculous idiocy in the project that’s, frankly, more than enough to stave off any DBA, end user, or developer. But I’ll limit my list to five, because clickbait.

PG Phriday: Secret of the Ooze

A few days ago, a developer came to me with that inevitable scenario that every DBA secretly dreads: a need for a dynamic table structure. After I’d finished dying inside, I explained the various architectures that could give him what he needed, and then I excused myself to another room so I could weep silently without disturbing my coworkers. But was it really that bad? Databases have come a long way since the Bad Old Days when there were really only two viable approaches to table polymorphism. Postgres in particular adds two options that greatly reduce the inherent horror of The Blob. In fact, I might even say its a viable strategy now that Postgres JSON support is so good.

PG Phriday: JSON and JSONB Revisited

With Postgres 9.5 on the horizon, I figured it’s a good time to see how things have advanced since my [intlink id='pg-phriday-functions-and-addressing-json-data']last dive[/intlink] into that particular ocean. This is probably particularly relevant since even MongoDB, a JSON-driven NoSQL database, is now partially powered by Postgres. A lot of people found that particular revelation quite shocking, but maybe they shouldn’t, given the advancements embedded within the last couple of Postgres releases.

PG Phriday: Functions and Addressing JSON Data

Fairly recently, a friend of mine presented a problem he wanted to solve with some JSON he had in a table. After he presented the end result he was trying to reach, I made the assumption that this would be pretty easy to do. But then I looked at the JSON Functions to try and find that quick fix. Though I read extensively and used rather liberal interpretations of the functions, there’s no way to directly manipulate JSON object contents with PostgreSQL.
