I looked a little bit for possible interactions between those two modules,
and almost immediately noticed that pg_stat_statements is not being polite
enough to call any previous occupant of the post_parse_analyze_hook.
That's not the bug we're looking for, since auto_explain does not use
post_parse_analyze_hook, but it's a bug nonetheless.
