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