GUC configuration

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.
