WHERE SHARDING; is new to me. Is it a Postgres-ism, or related to the script changes in data/perform-sql-updates.sh? Might be worth an inline comment?

It's nothing in PostgreSQL, sadly. It comes from a hack where I'm replacing SHARDING with the range of osm_id to shard over. I would have used a proper Jinja2 template, but that was going to introduce a lot of incidental complexity.

I'm not totally sure whether an inline comment would work there, or if it would have weird side-effects... I'll have to test and make sure.

Added comments in e684cd8, looks like they're correctly preserved through all the string mangling we're doing.

Is it a pain to name it something like $SHARDING and replace on that? Just thinking it might make it clearer, although the comment is good anyway :)
