Good News Everybody!
The book "PostgreSQL Server Programming" is finally out.
It covers programming done in server - functions, types, indexes, ... -
and not hacking the server itself.
Things covered are writing functions in pl/pgSQL, pl/pythonu and C, as
well as scaling with pl/proxy and packaging your code for distribution
as extensions.

for title at your favourite bookshop.
