Summary: Pull Request resolved: https://github.com/facebook/rocksdb/pull/12677 The patch contains two fixes related to printing `PutEntity` records with `ldb dump_wal`: 1) It adds the key to the printout (it was missing earlier). 2) It restores the formatting flags of the output stream after dumping the wide-column structure so that any `hex` flag that might have been set does not affect subsequent printing of e.g. sequence numbers.
