FW: Creating database links - Mailing list pgsql-admin

Hi Jorge,

What would be the syntax for extracting all columns from a database table using dblink?  Could this be used if you are
unsureof the structure of the table you're extracting from? 

Thank you in advance,
d

    This is what we're using , don't forget to install db_link module

    select * from dblink('host=1192.168.1.1 dbname=mydb port=5432 user=myuser password=my_password', 'select name from
country')as t1 (proname name, prosrc text); 


    Best Regards...

            Closest thing we've got is foreign tables based on the postgres_fdw
            foreign data wrapper (or you could use a different wrapper if you
            want to link to a non-Postgres database).
