Read recover rows

[Alejandro Carrillo <fasterzip@xxxxxxxx>]

Hi,

1) Anybody knows how to create a table using a table file? It isn't a fdw, is a file that compose the table in postgresql and get with the pg_relation_filepath function. Ex:
 
 select pg_relation_filepath('pg_proc');
 
2) Anybody knows a JDBC or a multiplatform code that let read the delete rows of a table without writing of a table file?

Thanks
