   I just did a planet export and it now takes a reasonable time to generate 
the mbtiles (2.5 days for 132G).
   
   Here is an excerpt of the log:

   The issue was related to poorly optimized postgresql queries that have been 
fixed in #753. The long queries are now logged with a warning to help user 
optimize the pipeline.
