> As you can see, the query has not been normalized. Is it a bug, expected or undefined behavior?
No, this behavior is expected. The ability to normalize a statement is
only available
during post_parse_analyze (pgss_post_parse_analyze), as this is when
we have access to
JumbleState.
In your example, pgss_post_parse_analyze is skipped and during the
subsequent \bind_named,
ExecutorEnd (pgss_ExecutorEnd) does not have access to JumbleState,
leading to the query to be stored without normalization.
It will be nice to make JumbleState available to all hooks, IMO.
