GUI Debugger for PostgreSQL on Windows

Hi,

This might be a newbie question but I'm wondering how, most of you guys, are 
debugging PostgreSQL on Windows (XP) ? Are you all using gdb? I want to 
develop a new data type and I'd like to trace code in a graphical interface. 
I have been trying very hard with Eclipse without success. Insight doesn't 
seem to work very well on Windows...

I can believe most of you are happy with gdb...

Thanks for any info.

Pierre
