[Tile-serving] [openstreetmap/osm2pgsql] Very slow node parsing on updates (caused by PG's jit) (#1045)

[Christian Quest]

Make sure you ANALYZE the tables after a PG upgrade, this can really help the planner.

FYI, I've submit a bug to the postgres dev team... here is the thread on the bugs mailing list:
