Good to know. I am playing with Finnish and Scandinavian data only and I set
keep PostGIS using WITH_OIDS as default and thus I get primary keys
automatically. Not really a problem for me, but those who are playing with
more data and perhaps have a remote database without db-admin rights need to
create the primary key field themselves. Primary key is compulsory for many
uses. But knowing the situation helps.

Right, did not remember that shop wan one of those extra tags that was added to
osm2pgsql.exe. It is possible to read map features page so that giving
shop=supermarket as an area is supported, but not all shop=something.
Osmarender seems to render it. For on-demand rendering it would be more simple
to keep all shops as points and perhaps colour the building according to
building=shop or building=commercial or the like. But I have understood that
now I can just edit the default.style file for having some own tags, for
example max_speed if I'd like to colour highways according to that.

Thanks for compiling. By the way, the final report is missing now, that used
to look like this
Node stats: total(2658737), max(312060206)
Way stats: total(175231), max(28408381)
Relation stats: total(836), max(51578)
