<p>Turns out that Nominatim needs the array indexes on planet_osm_rels after all. It does a lookup by member. So this causes a bit of a regression in Nominatim, see <a class="issue-link js-issue-link" data-error-text="Failed to load title" data-id="707821891" data-permission-text="Title is private" data-url="https://github.com/osm-search/Nominatim/issues/1978" data-hovercard-type="issue" data-hovercard-url="/osm-search/Nominatim/issues/1978/hovercard?comment_id=701743883&comment_type=issue_comment" href="https://github.com/osm-search/Nominatim/issues/1978#issuecomment-701743883">osm-search/Nominatim#1978 (comment)</a>. However, I think this is better fixed on the Nominatim side where we can just create the indexes we need.</p>
