I'm using PostgreSQL 9.3 running on Ubuntu Server.
I have 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 this function many times from my application, but something goes wrong with the disk assigned to my temporary tablespace and all threads were dropped. Now my big table 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 in this table?
Do you want to recover the dead data or the space that it consumes?
