In general, I don't think we want to increase the number of distinct tags.
Which command you finished running and whether you want a rowcount and/or
lastoid are orthogonal issues. We already have problems with there being
different commandtags for different versions of morally the same commands.
Take for example "SELECT FOR KEY SHARE" vs. "SELECT FOR NO KEY UPDATE" vs.
"SELECT FOR SHARE" vs. "SELECT FOR UPDATE".
