It also looks like a lot of performance improvements have arrived. With the article the other day about how an intern found a 4x speed improvements for SELECT queries, it gives me hope that amazingly postgresql still has plenty of room to be sped up.
Just the SSL ECDH key exchange alone should dramatically improve the speed to fetch data. Also, pg_prewarm should reduce the time of the first queries to hit the database once a DB is restarted.
Looks like some NOSQL/Document databases can be replaced with postgresql quite nicely.
Whilst there are some improvements in the full text search, it seems things like SOLR are safe... for now.
It's nice to see more steps towards multi-master too.
