PostgreSQL has a rich set of abstractions for inter-process communication, with names and sometimes ideas that may be new to those coming from general purpose programming environments. In this talk I will talk about the process model, and the main abstractions in the tool box for managing concurrency at a basic level in PostgreSQL, including:
and more. This will include some discussion of evolving implementation details, from a systems hacker point of view.
My goal is to provide an overview of these core tools that come up again and again in pgsql-hackers mailing list discussions about feature development and bugs in PostgreSQL. They are also part of the API available to extension writers.
