One of the hardest parts in building architecture for your project is to choose the DB.
The most important criteria are: Community Support, Performance, Replication, Supported Data Types, Indexes, Security etc.

In today's post I want to add few links with comparing two most popular relational databases - MySQL and PostgreSQL:

Indexes are the essential part of most of the databases. These data structures are used to optimize the performance of database queries. But duplicate, redundant, and unused indexes can dramatically reduce performance.

In the article Duplicate, Redundant, and Invisible Indexes by Percona you’ll find small tips about finding such indexes in MySQL and I hope reduce the time of some queries.
