RDS Connectivity

I travel quite a lot for work. Most of it is in the US and Europe, but I get around to other places as well. Most of the time, connectivity, while not the greatest, isn't that bad, or hard. I run a VPN on my phone and laptop. I can set up my RDS connectivity by getting whatever IP address I've been assigned, and I'm good to go. However, recently, for whatever reason, I could not make a connection to AWS RDS no matter what I tried. I even switched over to my phone. I dropped my existing database (which hurt, just a test database, but now I have to rebuild it). Nothing. I validated every single possible problem. I went through all the troubleshooting steps. Nothing. It's Nice to…

AWS RDS PostgreSQL Restore to a Point in Time

AWS, PostgreSQL, RDS

One of the single biggest reasons to go with a Platform as a Service (PaaS) offering like AWS RDS are the things it does for you, like making it really easy to restore to a point in time. Let's take a look at it. Restore to a Point in Time When connect up to the console and look at your databases, all you have to do is select the "Maintenance and Backups" tab to get details on what backups are being taken: That's the basics of what's happening with your backups. However, you can get more detail by choosing the "Automated Backups" page on the left: And now you see all the information about the backups. But the real magic to restore to a point in time is over on…

PostgreSQL and Instrumentation

PostgreSQL

I'm still learning PostgreSQL and one of the things I've been looking at a lot lately is instrumentation. What do I mean? Well, if you're in SQL Server, think, Dynamic Management Views (DMV), Extended Events, Query Store, <hack, spit> Trace <spit>. How do we know how long a query took to run? PostgreSQL can tell you, but, and this is one of those wild, cool, but, honestly, slightly frustrating things about PostgreSQL, not natively. Let's talk about it. Instrumentation If you connect up to a PostgreSQL database, you actually do have the equivalent of DMVs. It's called the Cumulative Statistics System. And yeah, it's a bunch of views on a bunch of functions. It displays all sorts of data about IO, tables, indexes, etc.. It will even show you acive…

Data Technology Learning Resources

AWS, Azure, Database Fundamentals, PostgreSQL, SQL Server

Hey all! Quick one here. Tracy Boggiano, awesome person that she is, has put together an interesting collection of data over on GitHub. It's titled DBA Resources, but it goes beyond DBAs. It's much more about the different data platforms on display. And, it's in Github. Create a pull request and you can add to it. Get your own blog on there, whatever. Anyhoo, worth a look. I'm going to do some contributions. Oh, AND, it's multi-platform, cause, isn't everything these days.

PostgreSQL Events – A Newbies Perspective: #PGSQLPhriday 014

PostgreSQL

For this month's #PGSQLPhriday 014 blogging event, Pavlo Golub has asked a pretty simple question: What do you think about PostgreSQL events? Prior to this year, I'd never attended an event focused on PostgreSQL. Heck, I'd never attended an event that had an intentional track or learning pathway, or whatever, focused on PostgreSQL. In the past year though, I've now attended four. As a complete newbie, let me tell you a little bit about the PostgreSQL community as I see it. Welcoming The very first word that comes to mind when I think about the PostgreSQL community is that it is welcoming. Like the SQL Server community that I've been practically living with for the last almost 20 years, the people who make up the PostgreSQL community are very kind,…

PGSQL Phriday #009: On Rollback

PostgreSQL

The invitation this month for #PGSqlPhriday comes from Dian Fay. The topic is pretty simple, database change management. Now, I may have, once or twice, spoken about database change management, database DevOps, automating deployments, and all that sort of thing. Maybe. Once or twice. OK. This is my topic. I've got some great examples on taking changes from the schema on your PostgreSQL databases and then deploying them. All the technical stuff you could want. However, I don't want to talk about that today. Instead, I want to talk about something really important, the concept of rollbacks when it comes to database deployments. Why Are Rollbacks Difficult? The entire purpose of your PostgreSQL database is to persist, that is to store, the data. Then, of course, offer up a way…

Why Put PostgreSQL in Azure

PostgreSQL

I've had people come up to me and say "PostgreSQL is open source and therefore license free. Why on earth would I put PostgreSQL in Azure?" Honestly, I think that's a very fair question. The shortest possible answer is, of course, you don't have to. You can host your own PostgreSQL instances on local hardware, or build out VMs in Azure and put PostgreSQL out there, some other VM host, or maybe in Kubernetes containers, I mean, yeah, you have tons of options. So why PostgreSQL in Azure, and specifically, I mean the Platform as a Service offering? Let's talk about it. PostgreSQL in Azure Let's assume for a moment that you're PostgreSQL expert (I'm not, but I do play one on TV). You know exactly how to set up…

#PGSQLPhriday 006: Wrap Up & Summary

PostgreSQL

Your mission, if you chose to accept it, was to share a single tip/hint/fact/something that you wish you'd known about PostgreSQL when you were just getting started learning it. Well, we've got several people who have put together some excellent posts. Let's go over 'em all, in no particular order. First up, Lætitia Avrot has a post all about the PostgreSQL documentation and it is well worth the read. I couldn't agree more with all her points. Plus, I love, love, LOVE the summary list of pointers to documentation broken down by role. Thanks so much for sharing all this. I also wrote a post about the docs. Lætitia covers them better. Next, Andreas Scherbaum has some very cool tips for using psql. My knowledge here is a bit slim.…

#PGSQLPhriday 006: What I Wish I Knew While Learning PostgreSQL

PostgreSQL

Well, for those who don't know me, I'm just barely started on my PostgreSQL journey. So, what the heck can I contribute to this conversation? Not much, but I do have one tip. It's about the official documentation and search engines. YaDuBiGo When you use Yahoo, DuckDuckGo, Bing, Google, or whatever search engine you use, what you don't get is a simple, "here are the pages you asked for". All the search engines use various mechanisms to surface you "here's the BEST and MOST POPULAR pages you asked for." What defines best in these circumstances? Most accurate? Maybe, maybe not. I've never worked for one of these organizations and they tend to keep their algorithms to themselves, for obvious reasons, both good & evil. However, I do know one thing…

One Thing You Wish You Knew While Learning PostgreSQL: PGSqlPhriday #006

PostgreSQL

I will not even attempt to hide it, I'm very much in the learning phase of my PostgreSQL journey. As such, I'm constantly picking up new facts. However, I'm interested in that one thing that you wish someone had told you. That tiny bit of "AH HA!!!" information that you have now, but it took you a while to find. Just that teeniest, tiniest slice of the behavior of PostgreSQL that proved to be a game-changer for you. In short, help me and all the others out there trying to learn this stuff. Make learning PostgreSQL just a little bit faster & easier for us. Please. Why am I asking? Because this is all a part of #PGSqlPhriday 006. What is #PGSqlPhriday and how do I participate? As to what…
