Hi PostgreSQL,

 I'musing PostgreSQL 9.3 running on Ubuntu Server. 

 Ihave a complex function to populate a big table, in order to improve performance;data is prepared in temporary tables before it will be inserted. I called thisfunction many times from my application, but something goes wrong with the diskassigned to my temporary tablespace and all threads were dropped. Now my bigtable statistics shows tuples inserted and its size is in order of gigabytes,but a simple SELECT has no rows, is there any way to recover the data inthis table?
