This chapter elaborates on the available clients for PostgreSQL. Clients exist in order to provide a user interface to the PostgreSQL server (also called the backend).
The two most accessible clients for PostgreSQL are the command-line driven psql and a graphical alternative, PgAccess. The psql client is installed by default, while PgAccess requires specification of the --with-tcl option during compilation of the PostgreSQL source code (as mentioned in Chapter 2).
