The Transactions page in the 20.2 DB console shows implicit transactions as explicit in the Transaction Details page.

This is an example of a transaction that was issued as an implicit transaction. Rollback statements used just to illustrate that an explicit transaction was not in progress.

root@snow:26257/defaultdb> rollback;
ERROR: there is no transaction in progress

root@snow:26257/defaultdb> insert into foo values (5);
INSERT 1
Time: 5ms total (execution 5ms / network 1ms)

root@snow:26257/defaultdb> rollback;
ERROR: there is no transaction in progress

root@snow:26257/defaultdb>

Repro:

1. Start a single node
2. Issue a simple implicit statement
3. View the Transactions page in the DB Console
4. View the Transaction Details page for the transaction
5. Notice the statement is listed as Explicit
