Docs and regression tests attached.
One slightly annoying thing is this:
---
regression=# declare foo cursor with hold for VALUES(1,2), (3, 4);
DECLARE CURSOR
regression=# declare foo2 cursor with hold for (VALUES(1,2), (3, 4)) as
foo(i, j);
ERROR: syntax error at or near "as"
LINE 1: ...e foo2 cursor with hold for (VALUES(1,2), (3, 4)) as foo(i, ...
---
Now, we can just rewrite the second query as:
---
declare foo2 cursor with hold for select * from (VALUES(1,2), (3, 4)) as
foo(i, j);
---
but it's not immediately obvious. Not worth busting up the grammar for it,
though. And, it's not spec.
