Hi to all

I have to disagree.
You cannot just divide PostgreSQL into various sections.
People tend to think that tuning is nothing more than setting some 
server side parameter which not true at all. Also, knowing something 
about writing C/C++ applications with PostgreSQL does not mean that this 
person will be able to write good software if he doesn't know about 
other aspects of the system.
PostgreSQL is a powerful system but it is still small enough to 
understand it and to be a DBA as well as a tuner or a C/C++ programmer.
I can understand your approach - it can be used for Oracle or let's say 
SAP but not for PostgreSQL.
If somebody wants to certify other people he has to know more about the 
system and there needs to be at least one expert who has enough 
experience to do the job.

Some people have asked for certification in the past but meanwhile I 
think that preparing a certification guide and all that stuff is not 
worth the effort.

	Best regards,
