If my Geth node crashes during normal sync or --fast sync, can the integrity of the node's blockchain database be guaranteed or is there a risk that some transactions or even blocks (in the case of a --fast sync) didn't get written to the node's filesystem?

I think the only real way to guarantee integrity of the data is if a SIGINT was issued and subsequently gracefully handled.

This previous answer details Geth's signal handling during the importing of the chaindata.

A "crash" wouldn't normally accompany a SIGINT (nor vice versa).
