postgres fdw create foreign table without specifiy columns need to create couple of foreign tables with a lot of columns from oracle.
I dont want to specify all cloumns by myself.
Is there a way to do something like this: 

create foreign table ALFSTK **(*)** SERVER server1 options (schema 'test', table 'ALFSTK');


Or is this not possible with fdw?

Thanks for your advices.
This is what IMPORT FOREIGN SCHEMA is for.  You can run it for a single table at a time if you want to.

oracle_fdw says it supports IMPORT FOREIGN SCHEMA, but be sure to read that section of the docs for more info.
