[HACKERS] Postgre inner work question

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
