pg_last_error -- Get the last error message string of a connection

Description

string pg_last_error ( [resource connection] )

pg_last_error() returns the last error message for a given connection.

Error messages may be overwritten by internal PostgreSQL (libpq) function calls. It may not return an appropriate error message if multiple errors occur inside a PostgreSQL module function.

Use pg_result_error(), pg_result_error_field(), pg_result_status() and pg_connection_status() for better error handling.

Note: This function used to be called pg_errormessage().

Parameters

connection

PostgreSQL database connection resource. When connection is not present, the default connection is used. The default connection is the last connection made by pg_connect() or pg_pconnect().

Return Values

A string containing the last error message on the given connection, or FALSE on error.
