What hit us in this case is the movement of a function (get_progname())
from libpq to pgport and now that certain binary applications were
pulling get_progname from libpq rather than pgport. So the API didn't
really change, just the place applications looked for symbols.

What also hit us is that people complaining about this during beta
testing were told just to recompile (which fixed it), but we didn't
realize that it prevented installs of 7.4 from working.
