Part IV. Client Interfaces
This part describes the client programming interfaces distributed with PostgreSQL . Each of these chapters can be read independently. There are many external programming interfaces for client programs that are distributed separately. They contain their own documentation ( Appendix H lists some of the more popular ones). Readers of this part should be familiar with using SQL to manipulate and query the database (see Part II ) and of course with the programming language of their choice.
