The PG docs for PREPARE TRANSACTION [1] don't say anything about an
empty (zero length) transaction-id.
e.g. PREPARE TRANSACTION '';

~
Meanwhile, during testing I found the 2PC prepare hangs when an empty
id is used.
Now I am not sure does this represent some bug within the 2PC code, or
in fact should the PREPARE never have allowed an empty transaction-id
to be specified in the first place?
Thoughts?
