We have an error situation in the update process (openstreetmap-tiles-update-expire). At certain times, the update process crashes and does not proceed. The error message in the file /var/log/tiles/osm2pgsql.log is shown below:

Reading in file: /var/lib/mod_tile/changes.osc.gz

DB writer thread failed due to ERROR: result COPY_END for planet_osm_polygon failed: ERROR: invalid input > syntax for type integer: "2.75"

CONTEXT: COPY planet_osm_polygon, line 26, column layer: "2.75"

The message above seems to indicate that a double value (2.75) is being written to the layer field of the planet_osm_polygon table, which is set to integer.

To work around this, we decreased the value of the maxInterval parameter in the configuration file /var/lib/mod_tile/.osmosis/configuration.txt And we manually increment the sequenceNumber value of the /var/lib/mod_tile/.osmosis/state.txt file, so that it advances in the update. We believe there may be some information recorded wrong in the update files, which are available at

However, this is impacting our environment as it requires a lot of technical intervention.

Our environment is Ubuntu 20.04 LTS. The osm2pgsql version is shown below:

osm2pgsql version 1.2.1 (64 bit id space)

Compiled using the following library versions:

Libosmium 2.15.4

Lua 5.2.4

We would appreciate if you can guide us on how to solve the problem.

Yours sincerely,

Something in your map style can't cope with non-integer layer values. You've not said what style it is, so we can't directly help with that, but maybe this example will help:

this line in a lua style file makes sure that only seinsible layer values are used for z_order and tthe lines below here in a lua style file try and guess at layers from invalid values. See other uses of "tonumber" in that lua style file.

One other point to mention, since your seeing this in openstreetmap-tiles-update-expire - are you definitely calling the lua transforms from that and not the C transforms?

For completeness, the offending data in OSM is here, and it's not "a bug in OSM" as such - anything that consumes OSM data needs to be able to consume whatever is there. Scroll to the end of the list in taginfo and you'll see all sorts of values there.
