Scalable Sequence for PostgreSQL
However, PostgreSQL caches the sequences per-connection (different from Oracle that caches in the instance shared memory). Sequences can be a bottleneck in case of a storm where all have a cold cache, and here is a workaround. Note that re-connecting in PostgreSQL is expensive for many reasons and better fixt that with a connection pool that is not too dynamic (if you need this, you should have a look at FlexiPool)

Creating an advanced search engine with PostgreSQL
I'm wondering if CrateDB [https://github.com/crate/crate] could fit your use case.

Distributed query execution in CrateDB: What you need to know
A logical execution plan does not take into account the information about data distribution. CrateDB is a distributed database and data is sharded: a table can be split into many parts - so-called shards. Shards can be independently replicated and moved from one node to another. The number of shards a table can have is specified at the time the table is created.
