Hi,
I am trying to use postgresql in a research
project. I need to add several new operators, some
will probably take more than 2 input tuple streams.
The new operator will be considered by optimizer
when estimating cost and choosing a plan.
Can anyone tell me how hard this will be? And
where is a good place to start?
Thanks.
Feng
