Experiences with extensibility

The existing server extensibilities in modern DBMSs have been
critical in our company's development of software products that
improve database performance for certain scientific computing
applications. We are planning to develop other products that will
utilize an extensible database engine, and so we would be grateful
for feedback on the following questions as they pertain to your
experience in developing PostgreSQL applications:

1. What types of extensibility (i.e., data types,
functions/methods, indexing, etc.) are available and convenient to
use in practice?
2. What types of extensibility (possibly already available in
other DBMSs) are currently missing in PostgreSQL?
3. To what extent was your choice of PostgreSQL as a development
platform based primarily on its extensibility features?
