<para>
Allow indexes on a partitioned table to be automatically created
in new child partitions (&Aacute;lvaro Herrera)
An <quote>index</quote> on a partitioned table is not a physical
index across the whole partitioned table, but rather a template for
automatically creating similar indexes on each partition of the
table.
</para>
<para>
If the partition key is part of the index's column set, a
partitioned index may be declared <literal>UNIQUE</literal>.
It will represent a valid uniqueness constraint across the whole
partitioned table, even though each physical index only enforces
uniqueness within its own partition.
</para>
<para>
The new command <link linkend="sql-alterindex"><command>ALTER
INDEX ATTACH PARTITION</command></link> allows indexes to be
attached to partitions. This does not behave as a global index
since the contents are private to each index.
INDEX ATTACH PARTITION</command></link> causes an existing index on
a partition to be associated with a matching index template for its
partitioned table. This provides flexibility in setting up a new
partitioned index for an existing partitioned table.
