[Talk-us] Coolidge Corner, Brookline, MA has wrong zip code

[Max Erickson]

So just to follow up, what happens is that nominatim treats items
tagged with "addr:postcode" but not "addr:housenumber",
"addr:housename" or some type of POI tag as sources of postcode data.

There are quite few objects that will match that pattern that probably
aren't intended to define post codes. This Overpass API query does an
okay job of flagging them:

It causes the server to run out of memory for large areas so just zoom
in and try again if that error happens. There's probably some more
tags to exclude but it already filters down to a manageable number of
objects.
