+ 1.2) Who controls PostgreSQL?
+
+ If you are looking for a PostgreSQL gatekeeper, central committee, or
+ controlling company, give up --- there isn't one. We do have a core
+ committee and CVS committers, but these groups are more for
+ administrative purposes than control. The project is directed by the
+ community of developers and users, which anyone can join. All you need
+ to do is subscribe to the mailing lists and participate in the
+ discussions. (See the Developer's FAQ for information on how to get
+ involved in PostgreSQL development.)
+
1.3) What is the copyright of PostgreSQL?
PostgreSQL is distributed under the classic BSD license. Basically, it
Via web browser, use http://www.postgresql.org/ftp/, and via ftp, use
ftp://ftp.PostgreSQL.org/pub/.
+ 1.6) What is the latest release?
+
+ The latest release of PostgreSQL is version 8.1.1
+
+ We plan to have a major release every year, with minor releases every
+ few months.
+
1.7) Where can I get support?
The PostgreSQL community provides assistance to many of its users via
Also check out our ftp site ftp://ftp.PostgreSQL.org/pub/ to see if
there is a more recent PostgreSQL version.
- 1.6) What is the latest release?
+ Bugs submitted using the bug form or posted to any PostgreSQL mailing
+ list typically generates one of the following replies:
+ * It is not a bug, and why
+ * It is a known bug and is known already on the TODO list
+ * The bug has been fixed in the current release
+ * The bug has been fixed but is not packaged yet in an official
+ release
+ * A request is made for more detailed information:
+ + Operating system
+ + PostgreSQL version
+ + Reproducible test case
+ + Debugging information
+ + Debugger backtrace output
+ * The bug is new. The following might happen:
+ + A patch has been created and will be included in the next
+ major or minor release
+ + The bug cannot be fixed immediately and is added to the TODO
+ list
+
+ 1.9) How do I find out about known bugs or missing features?
- The latest release of PostgreSQL is version 8.1.1
+ PostgreSQL supports an extended subset of SQL:2003. See our TODO list
+ for known bugs, missing features, and future plans.
- We plan to have a major release every year, with minor releases every
- few months.
+ A feature request usually results in one of the following replies:
+ * The feature is already on the TODO list
+ * The feature is not desired because:
+ + It duplicates existing functionality that already follows the
+ SQL standard
+ + The feature would increase code complexity but add little
+ benefit
+ + The feature would be insecure or unreliable
+ * The new feature is added to the TODO list
+
+ PostgreSQL does not use a bug tracking system because we find it more
+ efficient to respond directly to email and keep the TODO list
+ up-to-date. In practice, bugs don't last very long in the software,
+ and bugs that affect a large number of users are fixed rapidly. The
+ only single place to find all changes, improvements, and fixes in a
+ PostgreSQL release is to read our CVS logs messages. Even the release
+ notes do not contain every change made to the software.
1.10) What documentation is available?
Our web site contains even more documentation.
- 1.9) How do I find out about known bugs or missing features?

1.11) How can I learn SQL?
First, consider the PostgreSQL-specific books mentioned above. Another
We are free for all use, both commercial and non-commercial.

except those outlined in our BSD-style license stated above.
