You are aware that postgresql already has a cache, I presume ?
Typically the reason to reach for a second external cache is where the 
primary
database can't serve the total load : external caching is a form of 
replication
in that case. I'd recommend that you evaluate the performance of PG
for your application before concluding that it isn't going to provide
sufficient performance (it might, it might not, but you should really
find out before fixing on one plan).
