<p>Hmm, this is a bit unexpected. It seems you're still running the Lua script in the "old" world and not using the new flex backend at all!</p>
<p>According to <a href="https://github.com/openstreetmap/osm2pgsql/blob/master/docs/flex.md#command-line-options">https://github.com/openstreetmap/osm2pgsql/blob/master/docs/flex.md#command-line-options</a>, you would need to:</p>
<ul>
<li>Change <code>-o flex</code> to <code>-O flex</code></li>
<li>Replace <code>--style 'src/openstreetmap-carto/openstreetmap-carto.style' --tag-transform-script 'src/openstreetmap-carto/openstreetmap-carto.lua'</code> by <code>-S src/openstreetmap-carto/openstreetmap-carto.lua</code>. There's no need to provide a .style file, all the information is inside the lua script.</li>
</ul>
<p>I haven't tested --tablespace-slim-data and --tablespace-slim-index in detail.</p>
