      Start a 0.10 connector that takes a snapshot of a pg database.
      Once the snapshot is finished and streaming has started, check pg_stat_activity for the JDBC Driver connection debezium holds open.
      Verify that the state is idle in transaction.

    Description

      After taking a snapshot on a postgres db, a transaction remains open on connection that debezium holds open. Post snapshot, pg_stat_activity shows a row for the debezium connection that is in a state of idle in transaction. Ex:

      application_name    |        state        |                                                                     query                                                                      
------------------------+---------------------+------------------------------------------------------------------------------------------------------------------------------------------------
 PostgreSQL JDBC Driver | idle in transaction | SELECT relreplident FROM pg_catalog.pg_class c LEFT JOIN pg_catalog.pg_namespace n ON c.relnamespace=n.oid WHERE n.nspname=$1 and c.relname=$2

      There is a workaround, if the connector is deleted and restarted after the snapshot is finished, the state is idle.

      It appears this issue only affects the 0.10 release.
