For a long time we used PGS directly for coastlines at highzoom. This meant we didn't have blue sea at highzoom, everything looked like land. So I wrote the coastline checker so we had a good view of what coastline was uploaded already and whether it was in good state. In short order the US, Africa, Australia and most of Asia were uploaded and fixed. Since we like to have our oceans blue we decided to switch. There was plenty of warning and plenty of encouragement, but in the end it was decided not to wait until every last island was uploaded. So no, it's only been like this for a few months. On the plus side you can fix it yourself.

Francois It's not quite that simple. The area in question is quite a complex river delta, and it needed quite a bit of manual correction to get the coastline correct. You'd have to: 1) run the coastline script to generate data 2) compare the generated data from (1) to the partial data already in the database 3) delete the unused nodes which have been left over when someone deleted the coastline ways 4) fix the day generated in (1) so it was in the correct direction in all cases 5) upload the new data. It seems a long process to go through when the correct data is somewhere in the database if only it could be extracted.
