Probably you would hear different respose from serious users who are
willing to have usable HA systems. I have number of customers who are
using our HA systems (they use several technologies such as commercial
HA solutions, pgpool-II and Slony-I). The one of top 3 questions I got
when we propose them our HA solution is, "how long will it take to
do failover when the master DB crashes?"
