Hi David,

this sounds cool. Could you give some more hints how to do that? Is this a standard function?


No, its not standard but... you create an on-delete trigger which calls a function and the function is an external perl or c script. I am not a c expert but it took me 20 minutes to write a c function and integrate it in postgres. Its very good documented.

pgSQL also lets you write your stored procedures in many different languages as well. IIRC, it supports perl, c, tk, and something like ten others.
