Hi, My client application dies during a transaction ( insert into a table ). Next time when connect to psql again and try to operate on the same table, it's trapped in a deadlock scenario. Is there any way to unlock the table? And another problem is that if psql exit unexpectedly during a client application during which a new table is created, the transaction is rolled back, but a table with the same name can not be created anymore. How to solve this problem? Thanks a lot Zhou ************
