==== JetBrains IDEs - DataGrip, IntelliJ IDEA, PHPStorm, PyCharm, RubyMine, etc ... ====
http://www.jetbrains.com/
Windows, Mac OS X, Linux
JetBrains has a dedicated SQL IDE — DataGrip which can connect to PostgreSQL as well. It provides code completion, multi cursors, local query history, navigation, refactorings and language injection support.
https://www.jetbrains.com/datagrip/
Other JetBrains Products, for example, PHPStorm, IDEA, have built-in database plugin, and it has the same functionality as DataGrip.
After you configured the data sources of your project, you can easily create tables, foreign keys, indexes much easier than usual, because the IDE is very smart; for example by foreign keys it automatically sets the name of the key and the related columns. For me, it is so far the best experience by creating a basic database schema. Even with editable EER models was it slower...
By the settings of your data source you can configure the SQL dialect of your database. After that, if you want to add stored procedures or triggers, you will have code completion which is favorable too. So I think JetBrains products speed up your work if you exactly know what you want, and how can you make it.
For any JetBrains IDE, there is a free license for open source projects. For enterprise usage there is a 30 days trial, after that, you can buy a personal or proprietary license which is very cheap compared to other products.
