[GENERAL] Read recover rows

[Alejandro Carrillo]

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
