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.
}

Try EXEC SQL FETCH IN rowcur ...

That's one of the holes in our documentation. If you get inspired to
write, we would welcome a contribution of any sort (including just
your notes on syntax as you learn to use the preprocessor). Our doc
sources are in sgml, but if you want to just write flat files I'll
convert it for you...

FETCH IN should work as well as FETCH FROM. I think this is what standard
says. I once tried to add FETCH without IN but got some shift/reduce
conflicts. I haven't looked into it for quite some time, so maybe I can add
a compatibility rule. But don't bet on it.

Unfortunately not much. But there are some (5 to be precise) demo files in
the source tree.
