I need to know/read something about "subject".
Step by step, something like :
1. write sql files [including creation & functions/trigger/etc]
2. write "Dynamically-Loaded Functions"
3. test using psql sql files
4. embed sql file in C compiled file
5. Debug app
6. write GUI interface

Any help and app. code sample ?
Thanks
Lucian
