Re: [HACKERS] I want to change libpq and libpgtcl for better handling of large query results

As far as I understood, this seems to be another solution to the older
problem of speeding up the browser display of large results. The first one
consisted on nonblocking exec/blocking fetchtuple in libpq (the patch is
very simple). But the main point is that I learned at that time that
backend send tuples as soon as it computes them.

Can someone give an authorized answer?

PS. On the other hand, if someone is working on back/front protocol, could
he think about how difficult would be to have a async full duplex
connection?
