Send all replies to the list please.  In this specific case I'm not going to be of much help but others should be.  You are likely going to need to supply additional context.

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?

​Do you want to recover the dead data or the space ​that it consumes?
