Btw, -1 for the idea, as it would remove the possibility to tell that a new
major release incrementing the 1st digit of version number brings more
enhancement than normal major releases incrementing the 1st digit. This was
the case for 9.0, helping people in remembering that streaming replication
has been introduced from 9.x series.</pre></blockquote> I don't find bumping the major to be particularly helpful. 
Everyrelease brings major features - and some introduce major incompatibilities.<br /><br /> 8.4 introduced CTEs.<br />
8.3broke tons of client code with the removal of implicit casts to text.<br /><br /> It really depends on what features
youconsider more major/significant. Personally I don't think it makes sense to try to say "this release is bigger" in
Pg- at least not in terms of enhancement. I can see value in using this-release-is-bigger for "this brings more
breakage"- but would strongly prefer a smooth and continuous release numbering that doesn't confuse the heck out of
users.<br/><br /> I'm extremely tired of being told "I'm running PostgreSQL 8.x" or "I'm running PostgreSQL 9.x" and
havingto point out the version policy, the fact that there are four years and huge fixes/enhancements between 8.0 and
8.4,etc.<br /><br /> The version policy makes _no distinction_ between which digit changes in a major release:<br /><br
/>"PostgreSQL major releases include new features and occur roughly once every year. A major release is numbered by
increasingeither the first or second part of the version number, e.g. 8.2 to 8.3.<br /><br /> "Major releases usually
changethe internal format of system tables and data files. These changes are often complex, so we do not maintain
backwardcompatibility of all stored data. A dump/reload of the database or use of the pg_upgrade module is required for
majorupgrades."<br /><br /> and I strongly believe that we should drop the notion entirely.<br /><br /> ... <br /><br
