Development Based on libpq

libpq is a C application programming interface to GaussDB. libpq contains a set of library functions that allow client programs to send query requests to the GaussDB servers and obtain query results. It is also the underlying engine of other GaussDB APIs, such as ODBC. This chapter provides examples to show how to write code using libpq.
