[Tile-serving] [osm2pgsql-dev/osm2pgsql] Daylight Ingest and Slow Deletions (Discussion #2088)

[mboeringa]

@pyoung-sc ,

I now imported the latest v1.32 of Daylight. However, I am seeing a serious issue with the country / administrative boundaries, as added to the PBF using the osmium `apply-changes` option per Facebook instructions (I used osmium `merge` for the buildings).

As you can see, the country boundaries (admin_level=2) are garbled, and only Australia and a few other countries come out more or less unscathed. The majority of boundaries is missing. 

Admittedly, the result you see is based on a custom generalization workflow I developed myself, but I have thoroughly battle tested this workflow over the last couple of years importing country and official OpenStreetMap Planet downloads, and never before seen this particular issue, hence I am pretty sure the issue is not on my side.

Another indication that there may have been a processing error at Facebook's side, is that the link to the matching **coastlines-v1.32.gz** file, is broken and ends up on an XML error page (https://daylightmap.org/). This is not the case for the previous Daylight v1.30.

Before I contact Meta, can you confirm this issue?
