Martin Pitt has detected that the libpq API has changed incompatibly
between 7.4 and 8.0.  This has the effect, for example, that 7.4's psql
cannot run with 8.0's libpq.  Example:

$ LD_LIBRARY_PATH=/home/peter/devel/pg80/pg-install/lib /home/peter/devel/pg74/pg-install/bin/psql --help
/home/peter/devel/pg74/pg-install/bin/psql: relocation error: /home/peter/devel/pg74/pg-install/bin/psql: undefined
symbol:get_progname

I haven't looked further, but we have to fix this urgently, I think.
