Slony is a master/slave replication system that can improve overall read 
performance.  DRBD gives you a hot stand-by system.  Both of these are 
completely different goals, which can be implemented complementarily.

A WAL-based replication gives you about the same effect as a DRBD 
replication, but with DRBD you pass on all the responsibility to the 
operating system.  One guy at LinuxTag told be he manages his DRBD 
pairs using Linux virtual servers, which would mean that on some level 
you don't even notice that you have two machines running instead of 
one.  If have yet to figure that out, but it sounds quite nice.

Btw., it was probably me who told you about DRBD, but I didn't make that 
up myself.  A lot of people are currently using it.
