ETL Tools for PostgreSQL::

Definition: An ETL process data to load into the database from a flat file

A. Extract

B. Transform

C. Load

1. PGLoader -  Load .csv file

2. Benetl 1.8 - Load .txt or .csv or .xls file

3. Talend Open Studio => http://www.talend.com/index.php

4. Pentaho Kettle => http://kettle.pentaho.com/

5. Visual Importer => Data can be imported from flat files,Excel.MS Access,Oracle.Mysql.Interbase,PostgreSQL,oleDB,ODBC and DBF files.

6. CloverETL => http://en.wikipedia.org/wiki/CloverETL

Both [3 &4] of these ETL solutions have a lot of the same types of features:

• Both are Java based and run on Linux and Windows (Talend is Eclipse-based)
  
• Visual designers for creating the transformations
  
• Connectivity for a myriad of databases, including all the big DBs, text formats, etc.
  
• Supports distributing jobs across multiple servers if you are doing serious lifting
  
• Excellent error handling and error notification systems
  
• Active and helpful forums (Kettle is older and seems to have a larger community however)
  
• Free and open source
  
• They are complex enough to handle a lot of tasks, but not so much as to kill you
  
• There are versions of both (GeoKettle and Spatial Data Integrator) that are tailored for GIS

Not exactly an ETL tool, but I've recently felt a sense of liberation since switching to make/python/psql/wget... for my ETL needs. Make is probably the cornerstone as it handles dependencies (think foreign key ordering with schema introspection) and parallel loading in a very intuitive way.
