pg_last_error — Get the last error message string of a connection

### Descripción

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().

### Valores retornados
