mySQL is great for embedding in applications though?  Have they not read Oracle's license?

Sorry to say, this site is full of holes. The problem is explained in
section "I am familiar with this database".
How would people who don't know something be allowed to emit a judgment
about the compared products?

Does it say anywhere on that site if the people surveyed know both
databases well enough to judge these questions? I can't find anything
about that, and the site also ranks gin and martial arts, so I'm not
sure sure it has much value.

It seems to be based on the honor system.  When you click "Rank", it asks you what databases you're familiar with.  Then you can stack rank those databases across various questions.  It's possible people could lie and say they know about mySQL and Postgres when in reality they don't, but hopefully the overall results would be accurate.  Actually one of the reasons I posted it here was because I was hoping more database experts could weigh in with their opinions..

Probably a very useful site to note people's 'perceptions' - as
perceptions tend to influence peoples decisions, especially when people
feel overwhelmed by technical decision making.

Also note that for features that are obviously complicated or advanced,
Postgres tends to a lot better than MySQL.

For the above reasons, I think it may be of value to the pg community to
look at it in order to consider what are marketing messages should be.


Cheers,

It's like comparing BASIC to C. BASIC has a low threshold, but you will very
quickly bump your head against the wall.

MySQL, the BASIC of db engines?

I have used both MySQL & Postgres: I feel a lot more comfortable with
Postgres, as it seems to be both simpler and more sophisticated.  MySQL
has several DB engines for different purposes, Postgres has just one
that appears to be more capable than the collection of features from all
the MySQL DB engines combined.  In the last 12 years I've gone looking
for comparisons between them 3 times; and each time, Postgres comes out
better overall.

And I must add: even using InnoDB, MySQL allows violation of relational
integrity (just put it under heavy transactional load).
I've suffered this pain in the past even with MySQL 5.1. This problem
does not happens with PostgreSQL.
The only occasion I had duplications in PostgreSQL was during a heavy
data load. At that time, I used RSync to copy data to another server
with the command:

rsync -azv /var/lib/pgsql/9.1/data root@127.0.0.1:/var/lib/pgsql/9.1/


Do you see my mistake above? Yes, this causes duplicate records (and
after some time, complete database corruption in PostgreSQL).
Is just db admin stupidity (I can tell, because I was caused by my
self). Would be nice if we can shield PostgreSQL against my personal
silliness.

My tools are not good enough to cope with my own ineptitude - give me
better tools!  :-)

I saw lots of discussion about the results shown in the website. I would
say that it is always good to have something to start with. And I vote
for it.
