     As explained above, it is possible to create indexes on partitioned tables
     so that they are applied automatically to the entire hierarchy.
     This is very
     convenient, as not only[-will-] the existing partitions [-become-]{+will be+} indexed, but
     [-also-]{+so will+} any partitions that are created in the [-future will.-]{+future.+}  One limitation is
     that it's not possible to use the <literal>CONCURRENTLY</literal>
     qualifier when creating such a partitioned index.  To avoid long lock
     times, it is possible to use <command>CREATE INDEX ON ONLY</command>
