One of the key strengths of PostgreSQL is its extensability, and at the core of that are functions. In PostgreSQL functions can be used as an end in-and-of themselves, or they can be used to allow the creation of other custom SQL objects such as operators and aggregates.
This presentation will enlighten the audience on the vast array of capabilities embodied in PostgreSQL functions, and illustrate many of the key features through simple and real world examples.
