parameterized fetch - Mailing list pgsql-hackers

I've noticed that trying to parameterize a fetch statement via
ExecParams returns a syntax error:

fetch $1 from my_cursor;

This is not really a big deal, but maybe it should be documented which
statements can be parameterized and which can't (I take it that any
statement that can be prepared can be parameterized;

prepare test as fetch 1 from my_cursor;
also returns a syntax error;
