Gathers statistics about real reads and writes done by the filesystem layer. It
is provided in the form of an extension for PostgreSQL >= 9.4., and requires
pg_stat_statements extension to be installed. PostgreSQL 9.4 or more is
required as previous version of provided pg_stat_statements didn't expose the
queryid field.
