BTW, have you verified that it's actually worth the trouble to prepare
these commands? Given that there's no planning cost for a utility
statement, and hardly any parsing cost for one-word commands, I'm a bit
dubious that the prepared-statement machinery actually results in a win
compared to just issuing simple Query messages.
