You are welcome to hack on postgresql! From making queries faster (better plans, computing on graphic cards, column-stores,compiling queries) to making better the storage engine (column store, tokudb-like stores etc) to new type of indexes to new type of queries (ex increment jsonb fields even if they dont exist) to sharding it (and even different types of sharding (pg_shard, pg-xl)) to lowering the overhead (each row has 22bytes of overhead!) to so many different things that are listed here: https://wiki.postgresql.org/wiki/Todo https://wiki.postgresql.org/wiki/Todo.
