Hi everybody,
        i lost one file in my file system, it's file reference the one user table (table "x")... Are there some option to recover this table? (without any backup and database isn't archive mode).

 

 

Hi Fábio,

If you have no backup I do not see how to recover it, but you can recreate the table (only structure) by querying the system catalog (if it is working of course). 

Use a similar query do see some information about the columns of table:

SELECT * FROM information_schema.columns WHERE table_name = 'x';

To more information about system catalog see [1] and [2].
