Hi, I have a function that returns an SQL string as follows: CREATE OR REPLACE FUNCTION t1() RETURNS text AS $$ BEGIN RETURN 'SELECT * FROM mytable'; END $$ LANGUAGE plpgsql;
and I want to create a second function (t2) that will execute the string returned by t1() and return the results. I thought about using RETURN QUERY EXECUTE as documented here: https://www.postgresql.org/docs/9.6/static/plpgsql-control-structures.html but there's a note towards the end that says '/if a PL/pgSQL function produces a very large result set, performance might be poor: data will be written to disk to avoid memory exhaustion, but the function itself will not return until the entire result set has been generated./' Is there any other way I can achieve execution of the dynamic SQL from t1() without having the whole result set retrieved inside the function itself? note: My example above is simplified, my real t1() function takes some parameters and generates SQL depending upon those parameters.
