There is an interesting report (in English) about the use of free
Open-Source software in companies and public institutions in Germany, UK
and Sweden. (As Germany is one of the most important and largest markets
for Open-Source software)
This FLOSS report covers to some extend specific figures about
Open-Source DBMS, reasons why organizations have decided for OS DBMS,
market shares of OSS DBMS, etc. - PostgreSQL and MySQL are mentioned too
(see chapter 5.1.2 OSS used for databases, Page 37+).
The report has been made by Berlecon Research (http://www.berlecon.de)
in 2002, financed by the European Commission. Maybe you already know
this report, but for them who do not, I provide this report as PDF
temporarily at following URL:
http://www.go-gen.com/tmp/FLOSS1-Usage_of_Free_Open_Source.pdf
Hopefully, these information may be useful for better understanding the
needs of our customers, or the promotion of PostgreSQL.
Have a nice W/E
