The code for all nodes is in src/backend/executor.
I think that you will find it useful to look at the big switch
statements in ExecInitNode() and friends in execProcnode.c .
Yep, same as what I found in src/backend/commands/explain.c. Thanks. I'll keep
using what's in src/backend/commands/explain.c because I'm using the XML format
in explanation and so the nodes have human-readable names.
It's been pointed out before that plugins (like FDWs) can invent their
own explain nodes, so we'll never have a canonical list of such nodes.
cheers
