pg_last_error — Get the last error message string of a 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.
Nota:
This function used to be called pg_errormessage().
connection
Uma instância de PgSql\Connection.
Quando o parâmetro connection

ou pg_pconnect().
A partir do PHP 8.1.0, usar a conexão padrão tornou-se defasado.
