ECPG and FETCH

First of all, ECPG doesn't seem to recognise the FETCH command at all,
returning with Syntax Error (see below).

Secondly, are there any postgres specific Embedded SQL docs around
'anywhere'?
I've already have a few difficulties with subtle differences between
different precompiler syntax, and it's becoming frustrating.

eg:

EXEC SQL DECLARE rowcur CURSOR FOR
SELECT prod_id, name, format
FROM products
WHERE name like '%ABC%';

EXEC SQL OPEN rowcur;

for (i=0; i<5; i++)
{
EXEC SQL FETCH rowcur INTO :prod_id, :title, :format;
// Do something.
}
