Hi,

I am an MSc student in the department of Informatics and Telecommunications of the University of Athens and as part of my thesis I am examining some new cost models for DB optimizers. I have successfully changed the optimizer of PostgreSQL in order to implement these models, but I have stumbled upon a very little detail: until now I use some hardcoded values in my code which I would like to make accessible through GUC. After much googling the only relative pages I have found is about configuring existing PostgreSQL variables. Can anybody please provide some help? How can I add some new configuration variables using GUC?

Thanks in advance,

Thanos Papapetrou

You insist that there is something that a machine can't do. If you will tell me precisely what it is that a machine cannot do, then I can always make a machine which will do just that.
