Hello
execute doesn't set FOUND variable, but sets diagnostics variables.
you can:
create table foo(a integer);
insert into foo values(10),(20);
create or replace function f() returns void as $$declare rc integer;
begin execute 'update foo set a = a'; get diagnostics rc = row_count;
raise notice '%', rc; end; $$ language plpgsql;
postgres=# select f();
NOTICE: 2 f
---
(1 row)
