Here you can access PostgreSQL mailing lists for Postgres users and developers.
General discussion area for users. Apart from compile, acceptance test, and bug problems, most new users will probably only be interested in this mailing list (unless they want to contribute to development or documentation). All non-bug related questions regarding PostgreSQL's version of SQL, and all installation related questions that do not involve bugs or failed compiles, should be restricted to this area. Please note that many of the developers monitor this area.
Discussion for users on SQL related matters.

The PostgreSQL developers team lives here. Discussion of current development issues, problems and bugs, and proposed new features. If your question cannot be answered by people in the other lists, and it is likely that only a developer will know the answer, you may re-post your question in this list. You must try elsewhere first!
Translation announcements, coordination and discussions
This mailing list supports Round Robin Review during commitfests by allowing the CommitFest Mom to assign random patches to a list of volunteer reviewers.

Notification of git commits are sent to this list. Do not post here!
