Hi!

Does postgre execute the queries following a execution plan tree, where the
leafs are table scans, and the nodes are joins?

I'm looking for a database where I can get a cardinality from a partial
result of the execution... for example, print the cardinality of the results
until the next join operator use this result...

Thanks!
