Blog: PostgreSQL , p.6

We are delighted to repost the  article by Citusdata, and appreciate the recogintion of our contribution:  "Special thanks to the people at Postgres Professional  for contributing most of the full-text search, JSONB, and GIN index features in PostgreSQL, as well as the initial code for the Citus COPY feature"

Recently Robert Haas has committed a patch which allows seeing some more detailed information about current wait event of the process. In particular, user will be able to see if process is waiting for heavyweight lock, lightweight lock (either individual or tranche) or buffer pin. The full list of wait events is available in the documentation. Hopefully, it will be more wait events in further releases.

pg_pathman is distributed as PostgreSQL 9.5 extension and available at github

Recently, we got  access to a big server: IBM 9119-MHE with 8 CPUs * 8 cores * 8 threads. We decided to take advantage of this and investigate the read scalability of postgres (pgbench -S) at this server.
