" * Postgres' WAL and durability guarantees were enabled when the data was originally written. At commit time, writes to Splitgraph's `cstore_fdw` object files don't get reflected in the WAL (since `cstore_fdw` is implemented as a foreign table). Since the data is already in a PostgreSQL table, this is an acceptable tradeoff -- if the commit gets abruptly terminated, Splitgraph will restart it from scratch. Splitgraph itself doesn't commit its own metadata writes to PostgreSQL until after the image has been created.\n",
