If this is a prepared query, then that is a good guess.  You can see the
real plan that the application is getting in psql by explaining the
execution of a prepared statement like this:

PREPARE foo(int, text) AS SELECT blah FROM foo, bar WHERE foo.id = $1 AND ...
EXPLAIN ANALYZE EXECUTE foo(someval, another);
