this looks like a test infra bug: the systemTableWriter may add comments to any table in any db, including tables in the schema change db. But i don't think the schema change workload expects anyone else is manipulating objects in its database. we should prevent the systemTableWriter from operating on the schemachange db.

observed this log line:

07:00:58 mixed_version_backup.go:1257: removing comment from table: schemachange.seq_w4_193
07:00:58 mixed_version_backup.go:1329: error running operation: pq: relation "schemachange.seq_w4_193" does not exist
