      (Heikki Linnakangas)
     </P
><P
>      Although this oversight could theoretically result in a corrupted
      index, it is unlikely to have caused any problems in practice, since
      the active part of a GIN metapage is smaller than a standard 512-byte
      disk sector.

      respond to a notification before database updates made by the
      notifier have become visible to the recipient.

      specified by the SQL standard nor documented, it seemed better to
      remove it than fix it.

      when there were many not-yet-committed rows at the end of the index,
      which is a common situation for indexes on sequentially-assigned
      values such as timestamps or sequence-generated identifiers.
