Обсуждение: postgres vs mysql conventional wisdom

On this first day of the month, I thought it might be interesting
to re-visit the conventional wisdom about postgres vs mysql.

Do these seem like fair observations?


Storage engines - Advantage Postgres for having far more available.

 Postgre has such a wide range of storage engines to choose from --
 ranging from whatever proprietary backend Yahoo uses,
 to Fujitsu's proprietary storage engine; to PowerGres Plus's
 proprietary storage engine; to Netezza's hardware accelerated
 storage engine.  In contrast, MySQL only has a few to choose from.

Broad Developer base - Advantage MySQL for having a more distributed team.

 Postgres developers seem to be concentrated in a handful of companies.
 After various acquisitions, MySQL developers are scattered to the four winds.

Large company support - Advantage Postgres for having larger companies support it.

 Fujitsu ($46 billion 2009 revenue; 185,000
 employees) much bigger than that little company  that bought
 whomever bought MySQL ($23 billion revenue; 73000 employees).

Any more?
