I'd also be interested in the implications of the upcoming changes
as I'm currently running many different styles from the same
--hstore-all import, some of them using the OpenStreetMap Carto
style osm2pgsql tables directly, some using views based on these
instead to add extra columns not available in the base tables.
Would this still be possible with 4.0 style tables, plus an extra
set of views mapping hstore entries to the old v3 layout, or will
there be more substantial changes so that I have to start planning
for maintaining old and new style imports in parallel to be able
to continue using styles based on the older layout?
