generate graphs in the format supported by graphviz.
It's interesting, but I don't think it is suitable for a

Hi,
I'm interested in data representation and debug of optimizer routines. Thus,
I've changed the debug functions of allpaths.c to make a graphviz-like output
of RelOptInfo structure.
Any idea about this?
Is there some project or improvement like

However I have to say this graph you've generated is amazingly hard to

That is pretty cool.
It would help a lot to label the baserels with their names.
You might also want to move the RestrictInfo out of line so that it's
easier to see where the inner and outer joinpath arrows are going.
Humm. Maybe this is not easy to do in dot command
