Why make it so complicated?
There could be a guc to indicate that the client is interested in
progress updates. For the execution phase, elog(INFO,...) could be
emitted for each major plan node. (The client would probably run the
explain plan beforehand or it would be embedded in the elog).
During the downloading of the rows, the client would display the bar
relative to the number of estimated rows returned.
