-The osm2pgsql project added built-in JSON support after the tagged
-v1.4.2 release.  This change ([commit](https://github.com/openstreetmap/osm2pgsql/commit/94dae34b7aa1463339cdb6768d28a6e8ee53ef65))

-This is only a concern when running on a server where you install osm2pgsql
-from a package manager. Following the instructions in
-[MANUAL-STEPS-RUN.md](MANUAL-STEPS-RUN.md) installs the latest
-version of osm2pgsql from source and avoids this issue.
-Also, using the PgOSM Flex Docker image makes this a non-issue.
