Review comment:
In general I copied this entirely from the equivalent create table
statement. How does the syntax for `REPLACE TABLE` differ from that of the
existing `CREATE TABLE`? My understanding is `REPLACE TABLE` is exactly
equivalent to `CREATE TABLE` with the exception of not having an `IF NOT
EXISTS` option.
