<p dir="auto">You could do the <code>add_row()</code> in one of the process functions and set a global Lua variable when you have done so. But you shouldn't do tricks like that. For one I am not sure whether defining a table without id columns will work and, if it doesn't, you end up with a table with some kind of OSM id column and every time osm2pgsql sees a change it will try to delete the feature from that table, which adds more overhead.</p>
<p dir="auto">If you insist in doing this from Lua, you can use the Lua Postgresql package do access the database from there. That would be a cleaner solution at least.</p>
