The dbdel command removes key/data pairs from the database.
In the presence of duplicate key values, all records associated with the
designated key will be discarded.
The options are as follows:
-glob
The specified key is a wildcard pattern, and all keys matching that
pattern are discarded from the database. The pattern is a simple
wildcard, any characters after the wildcard character are ignored.
-txn txnid
If the file is being accessed under transaction protection, the
txnid parameter is a transaction handle returned from envtxn.
The dbdel command returns 0 on success, and in the case of error, a Tcl error
is thrown.
