Query:
select to_node from way_tags, way_nds where k = 'amenity' and v = 'bus_station'
and way_nds.way = way_tags.way group by way_nds.way, way_nds.to_node having
min(to_node);
CREATE TABLE "sys"."way_tags" (
"way" int,
"k" varchar(255),
"v" varchar(1024)
);
CREATE TABLE "sys"."way_nds" (
"way" int,
"idx" int,
"to_node" int
);
But because I don't want to show an active denial of cooperation I also provide
a trivial example:
select schema_id from tables group by schema_id having min(schema_id);
