PostgresCDC...Change Data Capture for PostgreSQL

Hey folks...this is a Change Data Capture solution for PostgreSQL that loosely-couples very nicely with Talend Open Studio. It does NOT use triggers to track changes to tables...instead, it uses PostgreSQL internals and a sampling algorithm. Changed rows are presented to TOS via views...TOS simply selects from the views to get changed rows from the source, then performs UPDATE/INSERT or INSERT/UPDATE data actions on the target. No schema modifications are necessary at the source, PostgresCDC is completely transparent.
Here's the URL for the open-source package and documentation:
http://pgfoundry.org/projects/postgrescdc
Give it a try, and if you like it, please post feedback so I can continue to improve it.

Re: PostgresCDC...Change Data Capture for PostgreSQL

Hi Dave,
I'm interested in trying your solution, I downloaded the sql script, but I couldn't register myself to pgfoundry, in order to get the documentation. (It gives me some server error, and it does for several days now).
Anyway, I wonder, if you could post the documentation in some form (attachment maybe) here at this forum.
Also would be great if you could explain how it couples to Talend exactly, as I'm pretty new to this subject (CDC).
Thanks and regards,
Zoltan

Hi Dave,
I have downloaded the postgrescdc package, but I'm not able to download the install instructions.
Could you please grant me access to the download link or email me the doc.
Appreciate your help!
