Ref-cursors usage is also along with functions, so mentioning them along
with PL/PgSQL docs looks more logical to me. However in context of SQL statements also Fetch can use internally
generated cursor names in quoted strings, so about that some description might be useful.
But again I don't know clearly the usage of it, whether such kind of functionality is
used by users or PG is expecting to get Fetch used in such contexts.
