pg_last_error — Get the last error message string of a connection
Description
string pg_last_error ([ resource $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
connectionis 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.
