Nej, Postgresql er en fuldblods database, det er mysql ikke.
Bare et par få ting:
- I postgresql har transaktionerne acid egenskaberne (atomic,
consistent, isolatable, and durable)
Og mht. benchmarking, så er der en enorm usikkerhed, da hastighed
afhænger af mange ting (fx. typen af queries, om du er i stand til at
optimere designet osv..)...
Det kan siges som denne joke (men den er nu ikke helt ved siden af :)

If someone ask's you how do you compare the features and capability of
these three popular SQL servers:
Oracle, PostgreSQL and MySQL ??
Then comes the answer in layman's terms:
"A Elephant, Powerful White Horse, Fast Hare (Rabbit). Please tell
me
which animal you want ??"
Oracle = Elephant, Big and hefty but very bulky
PostgreSQL = Powerful White Horse, top breed horse (I love riding
horses)
MySQL = Fast running Rabbit (Hare), I like rabbits as pets, very
decent
animals!!
Oracle, PostgreSQL are in development for the last 22 years. Both had
originations in University of California, Berkeley.
Both are very mature, ACID compliant (Atomicity, Concurrency,.....)
and
are robust.
MySQL is like rabbit, it runs fast and can be a good pet.
But see, the speed is NOT at all important when it comes to SQL server
-
it is the ACID compliance, Data Integrity
and robustness and features and language interfaces which are
important.
You must not compare Elephant with Hare (Oracle with MySQL)
But the best among these three animals is - White Powerful Horse!!
(PostgreSQL !!)
Why do you think every person is waiting in a long queue to get a ride
on "White Powerful Horse" (PostgreSQL) ???
Every person on the planet wants to ride on PostgreSQL !!
