Looking for Good and Easy-to-use Reporting Tool

Can anyone recommend a good, easy to ease and inexpensive reporting tool for accessing and manipulating Postgre database/table? The key features I am looking for with this tool are as follows:

* Require less programming effort. I am trying to stay away from having to write sophisticate programming language, such as Java or .Net
* Allow to bundle SQL commands in store procedure like style.
* Allow to evaluate conditions of SQL result set and trigger alert email based on preset threshold.

Thanks.
Alan
