Description

sst_dump on packed rows can fail to show packed row data if --formatter_tablet_metadata is not provided:

SubDocKey(DocKey(0x965d, ["\xa1\xa4\x9d\x9a\xfa\xb1A=\xbd\x93\xebM\xf6\xcct\xa9"], []), [HT{ physical: 1688765805754590 w: 3 }]) -> Not found (yb/dockv/schema_packing.cc:216): Schema packing not found: 0, available_versions: []

Documentation should be improved around this. At the same time, it would be nice if sst_dump itself prints a dedicated message hinting about the lack of --formatter_tablet_metadata.

Contributor guide

Research direction
Find the sst dump source file where the schema packing error is printed. Add a condition to check if formatter tablet metadata is missing and print a hint. Then update the documentation (likely in the sst dump README or man page) to mention the flag.
