[ Sorry, I deleted Tom's reply.]
Tom, you mentioned suppressing the WARNING on COMMIT of an empty
transaction would make it hard to know when you are in a transaction,
but I was suggesting suppressing the warning only when autocommit was
off, so by definition you are always in a transaction, sort of. You are
in a transaction, but perhaps an empty one. Should it be OK to issue a
COMMIT of an empty transaction when autocommit is off?
