postgresql - Where can I find a description of plan nodes? -

i'm working way through postgres query plan first time.

i'm having problem because don't seem able find documentation describes each of plan nodes are. in many cases, name provides me reasonable guess, in several name of plan node generic me have confidence in it.

where can find list of types of plan nodes, descriptions of each?

chapter "56.1. row estimation examples" explaines lot, take look.
