Summary:
Partially port pg_regress test incremental_sort.  Omit the queries
related to parallel queries because YB currently only supports that in
colocated databases.  Temporarily switching to a colocated database at
that moment doesn't work well since queries depend on the tenk1 table
that was created in test_setup.  And running the entire schedule in a
colocated database is currently difficult since the Java regress test
runner does not currently support running with a different database.

    ./yb_build.sh fastdebug --gcc11 daemons initdb \
      --java-test TestPgRegressPgDml
