          If true, this logical replication slot supports decoding of two-phase
          commit. With this option, commands related to two-phase commit such as
          <literal>PREPARE TRANSACTION</literal>, <literal>COMMIT PREPARED</literal>
          and <literal>ROLLBACK PREPARED</literal> are decoded and transmitted.
          The transaction will be decoded and transmitted at
          <literal>PREPARE TRANSACTION</literal> time.
          The default is false.

          Decides what to do with the snapshot created during logical slot
          initialization. <literal>'export'</literal>, which is the default,
          will export the snapshot for use in other sessions. This option can't
          be used inside a transaction.  <literal>'use'</literal> will use the
          snapshot for the current transaction executing the command. This
          option must be used in a transaction, and
          <literal>CREATE_REPLICATION_SLOT</literal> must be the first command
          run in that transaction.  Finally, <literal>'nothing'</literal> will
          just use the snapshot for logical decoding as normal but won't do
          anything else with it.
