RE: Error: "remote query result rowtype does not match the specified FROM clause rowtype," on remote function call

I figured it out, you have to specify the type twice, once inside the remote call and once outside.

Like this:

SELECT * FROM dblink('conn_str', 'select public._test1() as x(a int ,b int)') as x(a int ,b int);

Not optimal and not readily discernible, but there it is.

Thanks for your response!

Do not have time to spin a test up at the moment, but what happens if you do?"

SELECT *

FROM dblink('conn_str', 'select public._test1();')

as x(a int ,b int);
