QUERY PLAN

--------------------------------------------------------------------------------------------------------------------------------
Seq Scan on planet_osm_ways (cost=0.00..1662990.31 rows=22160666 width=4)
(actual time=496448.422..496448.422 rows=0 loops=1)
Filter: pending
Total runtime: 496448.455 ms
This suggests that the table statistics are very out of date (22m rows
expected vs 0 actual). I suggest ANALYZEing the table and trying the
diff import again.
