'Jonathan Corbet, writing at LWN:

In the fast-moving open-source world, programs can come and go
quickly; a tool that has many users today can easily be eclipsed by
something better next week. Even in this environment, though, some
programs endure for a long time. As an example, consider the
PostgreSQL database system, which traces its history back to 1986.
Making fundamental changes to a large code base with that much history
is never an easy task. As fundamental changes go, moving PostgreSQL
away from its process-oriented model is not a small one, but it is one
that the project is considering seriously.

A PostgreSQL instance runs as a large set of cooperating processes,
including one for each connected client. These processes communicate
through a number of shared-memory regions using an elaborate library
that enables the creation of complex data structures in a setting
where not all processes have the same memory mapped at the same
address. This model has served the project well for many years, but
the world has changed a lot over the history of this project. As a
result, PostgreSQL developers are increasingly thinking that it may be
time to make a change.'
