Jeff Davis I'll be showing how the extensible pieces of PostgreSQL fit together to give you the full power of native functionality -- including performance. These pieces, when combined, make PostgreSQL able to do almost anything you can imagine. A variety add-ons have been very successful in PostgreSQL merely by using this extensibility. Examples in this talk will range from PostGIS (a GIS extension for PostgreSQL) to DBI-Link (manage any data source accessible via perl DBI).
