PostgreSQL Review

I prefer it over MySQL or MariaDB because you can create several databases with many schemas. It needs to be able to cluster.

What is most valuable?

It is an open source solution and that is a database engine very powerful. Besides it is highly configurable. I prefer PostgreSQL over MySQL or MariaDB because you can create several databases with many schemas and create roles like owners, and not only grants over tables, or procedures. On the other hand its very easy and intuitive to administrate the connections by hosts, databases, and roles.

How has it helped my organization?

PostgreSQL is a powerful dateserver although not like Oracle. So we can make many developments in a cheaper way with high availability. Besides, its very useful tool for debugging with a soft learning curve.

What needs improvement?

It needs to be able to cluster. We have implemented the high availability with a master-slave mode and one host in only read mode. This is the worst feature of this product and the quality sign of Oracle.

For how long have I used the solution?

I have been using PostgreSQL server for three years.

What was my experience with deployment of the solution?

The upgrade from v8.4 to v9.3 was a little hard, but this was executed finally well.

What do I think about the stability of the solution?

We had no issues with the stability.

What do I think about the scalability of the solution?

We've had no issues with scaling it for our needs.

How are customer service and technical support?

I've not had to contact them.

Which solution did I use previously and why did I switch?

I use MySQL, MariaDB, and Oracle. I chose PostgreSQL or others depending of the project. For Java implementations I prefer PostgreSQL, and for PHP development, I prefer MySQL or MariaDB,

How was the initial setup?

In my opinion the initial setup is easier than MySQL because it is more intuitive, but you must to edit a couple of config files, and become more aware of the entire infrastructure.

What's my experience with pricing, setup cost, and licensing?

It's open source code, so you get it for free and need to contribute to debugging errors and improving the code.

What other advice do I have?

Be patient! Like most open source tools, this requires commitment and a little knowledge.
