This has a problem when using any authentication other than trust or
ident.

Anything using libpq will hang, because the client will go into a loop
while connecting. The following patch simply comments out two lines (a do
and a while), removing the loop. Going through the new scheme, I can't see
why this do..while loop is in there.
