Error in DESCRIBE PLAN SELECT COUNT(*) FROM table on running server

[nicktobey]

Connecting to a running server and running a query of the form DESCRIBE PLAN SELECT COUNT(*) FROM table results in an error:

Error 1105 (HY000): result max1Row iterator returned more than one row

This only happens when connecting to a server, and not when running dolt sql locally.

This seems to be happening because the presence of the COUNT expression causes the analyzer to set the sql.QFlagMax1Row flag, but the DESCRIBE statement produces a row for each line in the plan.
