Interesting. I have been looking at PostgreSQL also. I was looking at
replication from Oracle to PostgreSQL, this is a blog I wrote for my
current employer on my proof of concept.

Mark,
just an addition regarding the necessary space reorganization in postgres:
the rdbms uses a multiversioning mechanism that stores different historic
versions of a row in the heap table structure - and has to keep them
available until the interested transactions are closed. As a result
frequent physical reorganizations are necessary and they are done by the
VACUUM command (or the auto_vacuum daemon):
https://devcenter.heroku.com/articles/postgresql-concurrency. That's
certainly not as sophisticated as Oracles undo treatment - but it works
(and has been around much longer than a sound MVCC in SQL Server for
example).
Having worked with postgres for some years (though much shorter and less
intensive than with Oracle) I would say that it deserves the good
reputation. The rdbms is very robust, shows a solid performance and
conatins lots of features.

As far back as I can remember MySQL required a license for legal
commercial use. It was only free for personal use if you read the
license. The commercial license however was pretty cheap. I think it was
a $500 flat fee.
I have never used PostgreSQL but I have looked into it in the past. The
product has a pretty good reputation. When I looked at it (years ago) I
remember seeing one major drawback which had to do with how delete
operations were handled. I cannot remember the details and it may have
only applied to the index entries but rows were only logically deleted and
you had to run maintenance to physically remove the data and make space
available for reuse. This is likely no longer true.

I think the first problem is if it is going to become suddenly commercial,
and that will be the same than equal for that is better to stay in Oracle,
Maybe I'm wrong but I remember that happened with mysql before Oracle
bought it. It was free and one day you had to pay for it.

Q: What company owns PostgreSQL?
A: None. We are an unincorporated association of volunteers and companies
who share code under the PostgreSQL License. The PostgreSQL project
involves a couple dozen companies who either support PostgreSQL
contributors or directly contribute corporate projects to our repository.
Some of our major corporate sponsors are on the sponsors page, and there
are many more companies who contribute to the project in other ways.
I don't know if this will guarantee this will be always free, but atleast this reduces the opssibility it becomes a commercial application, and
will be free more time.
Here is a quote about gardner and postgresql
and I think this one of the business that offers support to postgresql
http://www.enterprisedb.com/products-services-training/products/postgres-plus-advanced-server
http://www.briefingsdirectblog.com/2009/06/postgresql-delivers-alternative-for.html
Potential MySQL customers who are wary of the database's future under
Oracle stewardship have a possible alternative in Postgres Plus, an open
source alternative from EnterpriseDB, says that company’s CEO, Ed Boyajian.
I think it touches the problem that open sources database can becomecommercial database.

Hello, please can some one share experience on postgres sql :)
Now standard one has died and customers has to move to standard, I am
curious about postgresql, specially afters it was recommended.
about any hidden and misterious detail, for small business
1. Customers
I understand they can pay support, so they can perceive as something
serious for their companies.
2. Development
I had seen is strong enough
3. vs Oracle standard edition
I don't think there is too much to compare with enterprise, but maybe with
standard
Thank you very much for any comment :)
