Hi,
PostgreSQL ile Programlama [Programming with PostgreSQL], is a book
looks through how to connect a PostgreSQL database using C, PHP and
Python interfaces.
Book surveys every interface deeply with
- introduction examples,
- supplied functions,
- case studies on frequently met problems.
Book is written in Turkish and distributed freely under GNU FDL
license. A copy of the PDF is available at
http://www.students.itu.edu.tr/~yazicivo/doc/postgresql-ile-programlama.html
Regards.
P.S. I've made this announcement in regional pgsql-tr-genel mailing
list too, but thought it would be good to know for PostgreSQL family
that such an extensive documentation is freely available for
PostgreSQL.
