Re: About PostgreSQL certification

Hi Theo

I find your statements about Postgres being a huge business risk pretty laughable. First of all, Postgres is based on SQL92 and SQL99 standards which means that most scripts are pretty much the same compared to MSSQL and Oracle. The only thing I have seen to learn are the postgres datatypes. Big deal! PGAdmin III will write most scripts for you and that too is pretty much free. I dealt with it when we started learning and using postgres. I only had experience in Oracle and MSSQL.

Also comparing Postgres to MYSQL is also pretty funny, since there are instances of MYSQL LOSING databases due to corruption because they do not have PITR and their transaction rollback feature did not work properly last time I checked. This is really a issue of people being close minded to great database software and not being able to sell it to their superiors.

This is the way I sold postgres to my boss. It is opensource (low cost), all the features of MSSQL and then some, WAY FASTER than MSSQL on a BSD platform, very good recovery when the database gets corrupted (this happens to all databases from user error usually), and lastly you can always migrate the data to another database if you don't like postgres in the end.

I can't find 500, let alone 1000, people with extensive postgresql
experience in an enterprise environment. Oracle has an order of
magnitude more. MySQL even has better numbers than postgres in this
arena. If you only want to hire people with extensive experience,
you're exposing yourself to an enormous business risk by adopting
postgres. You'd have to hire out to a consulting company and if too
many do that, the consulting company will have scaling issues (as all
do).

The upside of Oracle is that I can hire out to a consulting company
for some things (particularly challenging scale or recovery issues)
and get someone who knows their way around Oracle reasonably well
(has performed _real_ disaster recovery in a hands on fashion,
performed hands-on query tuning, database sizing exercises, etc.) by
simply finding someone who is Oracle certified (all of those things
are part of the Oracle certification process). Granted, just because
someone is certified doesn't mean they "fit" or will excel at the
problems you give them -- it's just a nice lower bar. Granted you
can make a name for yourself as an expert without getting a
certification, but if you've made a name for yourself, you aren't
likely to be on the job market -- which is really my point. Oracle's
certification programs have helped Oracle considerably in gaining the
number of Oracle professionals in the job market. PostgreSQL
certification has the opportunity to do the same and in doing so
increase overall PostgreSQL adoption. That's a good thing.
