Hello,
you should execute your select statement as an dynamic query, because plpgsql assumes
that there is valid / parseable query (and not a string containing a query) after the
"IN".
( the skeleton for iterating on the result of dynamic queries)
FOR record | row IN EXECUTE text_expression LOOP
statements
END LOOP;
so you may use this as follows:
FOR each_row IN EXECUTE ''select * from '' || table_name LOOP
raise notice 'row';
END LOOP;
I don't test it, so maybe there are some mistakes in it.
It's possible too, that you must prepare your query itself into a text variable before
use in FOR IN EXECUTE LOOP.
I suspect that EXECUTE was added in v7.1.
hope this helps,
Papp Gyozo
