* The command populates up to the highest known block number
* The anticipated use case is that the listener will be running
in parallel to the populateBlocks command
* This will mean that the listener is responsible for picking up
new blocks, and the populateBlocks command is reposible for
historical blocks
* Reformat SQL statements
