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. http://slony.info/documentation/logshipping.html 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?
