Don't do that.
In particular, never put more into a single database transaction
than is required for integrity; and there is no apparent reason why
running a series of "SELECT 1" statements needs to be in a single
transaction. (It's not blindingly obvious why you would want to do
it in general, but I can imagine it possibly being useful for
monitoring purposes.)
