Now that I've spent some time away from this, I'm reconsidering why we are
going through all the trouble of semi-jumbling SET statements. Maybe we
just keep it simple and everything becomes "SET myvar = $1" or even "SET
myvar" full stop? I'm having a hard time finding a real-world situation in
which we need to distinguish different SET/RESET items within
pg_stat_statements.
Cheers,
Greg
