I had to rebase the patch against current (today morning's) GIT, since
there were a few changes against ECPG in the meantime.

The old contents of my GIT repository was removed so you need to
clone it fresh. https://github.com/zboszor/ecpg-readahead.git
I won't post the humongous patch again, since sending a 90KB
compressed file to everyone on the list is rude. You can pull
the commits individually from the above repository. For the same
reason, I won't add the DECLARE CURSOR command tag change
separately since this is also part of this big feature.

I have reordered some patches, like some independent bug fixes
against the ECPG parser and regression tests. The backend change
is also added early.

Best regards,
Zoltán Böszörményi
