Thanks for your suggestions; sorry I've taken so long to get back to
them, but I haven't had time to work on pgasync until now...

I've patched that in, thanks.

This is fixed.

Nope, I don't think so.

This is fixed as well.

It's not trival to determine whether or not something gets resolved.  If
it's a keyword argument situation, then I need to search the format
string for some variation of %(keyword)s.  If it's just tuple-style,
then I need to count the number of %s/d/whatevers and determine whether
or not it's beyond the limit.

This seems ugly, and needlessly expensive for a corner case; I think the
right answer is, only pass things to format() that are intended to be
formatted and made safe for insertion into SQL.

But, then again, maybe I'm misunderstanding you.
