Hi for all,

Please,
Normaly when some SGBD exec the algoritm Nest-Loop Join, there are diferences about the space(buffer) for outer table and inner table. So, I want know where Postgres define the number for this spaces (buffers)? And can I change it?

This is very important to me.

Thanks,
I hope that somebody can help me.

Daniel
