Some time ago I looked for a such hook. My case was to log failed access
permissions checks. I didn't find a way to do it, except adding a
narrow-focused hook within ExecCheckRTPerms().

There is ErrorContextCallback. Context callbacks are called when an
error was raised. But I don't think that it is a good approach for
pg_stat_statements cases.
