+ 1.6) What is the most recent release?

3.6) Why do I need to do a dump and restore to upgrade between major
PostgreSQL releases?
- The PostgreSQL team makes only small changes between minor releases,
- so upgrading from 7.4.0 to 7.4.1 does not require a dump and restore.
- However, major releases (e.g. from 7.3 to 7.4) often change the
- internal format of system tables and data files. These changes are
- often complex, so we don't maintain backward compatibility for data
- files. A dump outputs data in a generic format that can then be loaded
- in using the new internal format.
+ The PostgreSQL team makes only bug fixes in minor releases, so, for
+ example, upgrading from 7.4.8 to 7.4.9 does not require a dump and
+ restore; merely stop the database server, install the updated
+ binaries, and restart the server.
+
+ All users should upgrade to the most recent minor release as soon as
+ it is available. While every upgrade has some risk, PostgreSQL minor
+ releases are designed to fix only common bugs with the least risk. The
+ community considers not upgrading more risky that upgrading.
