[libpostgresql-jdbc-java] 12/22: Backport patch to work around a server bug. Server incorrectly handles the following: select 1; commit; set autocommit true; If this is submitted in one call to the server (the select 1 doesn't start a new transaction like it should), however if the select 1 is sent as a separate call then it works correctly.

    Backport patch to work around a server bug.  Server incorrectly handles the
    following:  select 1; commit; set autocommit true;
    If this is submitted in one call to the server (the select 1 doesn't start a
    new transaction like it should), however if the select 1 is sent as a separate
    call then it works correctly.
