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.
Actually it sort of is, once I started working on a test:
select * from public._test1();
ERROR: a column definition list is required for functions returning
"record"
LINE 1: select * from public._test1();
Have you looked at postresql_fdw?:

Thanks for your response!

This is my *remote* function:

END$function$;
This is my *local* function call:
SELECTx.a, x.b
FROMdblink('conn_str', 'select public._test1();')
asx(a int ,b int);
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);
This is the error thrown:
ERROR: remote query result rowtype does notmatchthe specified
FROMclause rowtype
Question:
Since DBLINK requires that I define a schema to place the function's
return items, how do I make the call to recognize a record type being
returned by the function.
Thanks!
