Why are you avoiding triggers? One solution might be to use Slony to
just create the log, and then read the log of events into memcached
rather than another PostgreSQL instance.

Those logs might be easier to process than the WAL.
Also, why do you need to intercept the WAL writes, and not just read
from a WAL archive? Does this need to be synchronous?
