Обсуждение: Extensibility features in PQSQL
Hi all,
I am interesting in understanding the extensibility features available in PostgreSQL. For instance what it takes to define a new operator or a new index and in particular what goes into the query optimizer in that case.
Please kindly point me to some useful resources on this.
Thanks and Regards,
Danushka

Postgres documentation is really excellent. http://www.postgresql.org/docs/9.1/static/extend.html should get you started.
