Osmosis/JXAPI is looking for some pgsnapshot-specific things (including
schema version numbers, tags stored in an hstore, etc.) that won't be there
unless you heavily modify osm2pgsql.
As I said earlier, JXAPI is meant *specifically* to generate OSM XML and
nothing else. I would recommend that you not use JXAPI as you're not trying
to generate OSM XML output.
