Append mode isn't supported about osm2pgsql-tuner

[rustprooflabs]

Aha - I had forgotten that during the first run of osm2pgsql when you want to be able to use --append later, you need to just run with --slim without --drop. Later runs of osm2pgsql you use --append. It seems the tuner should require a second parameter for 1st run vs. 2nd run, b/c the 2nd (and later) run needs --append.

Add first-run parameter? Then it's only needed the first time, making subsequent runs able to use the simpler command. I think subsequent runs will outnumber 1st runs by a decent margin.

I verified that running osm2pgsql with --append on an empty database fails.

This has been resolved for quite a few months now. Closing.
