[OSM-talk] Oh dear - planet has duplicate id's

[David Earl]

Oh dear, today's planet file contains two pairs of duplicate segments: they
have the same id. Surely id's are unique, yes? Isn't that the point? It
doesn't look like they are new, but it wasn't like this last week or I'd
have noticed.

(There may be others, but my program crashed trying to do an insert on a
duplicate primary key)

Excerpt below... 18591604 and 18591605 are the culprits, and this is a
contiguous section of the file.

(Also, note that 18591606 doesn't have any useful tags and 18591607 is
empty.)
