There's another bug on transactions. If one drop a table inside a transaction
and then change his mind and rollback work, the table structure is restored
but data are lost.
Take a look...

prova=> begin work;
BEGIN
prova=> lock table a;
DELETE 0
prova=> select * from a;
  a
---
  1
 13
134
(3 rows)

prova=> drop table a;
DROP
prova=> select * from a;
ERROR:  a: Table does not exist.
prova=> rollback;
ABORT
prova=> select * from a;
a
