For schemas where rows in one table reference rows in another, that time spread means the export can capture parent rows whose child records were not yet committed, or child records whose parents were deleted during the export window. The dump file looks intact until the import runs and foreign key constraints reveal the mismatch, or an ETL pipeline reports orphaned surrogate keys.</p>
