Recreate all indexes of the specified schema. If a table of this
schema has a secondary <quote>TOAST</quote> table, that is reindexed as
well. Indexes on shared system catalogs are also processed.

<term><replaceable class="parameter">name</replaceable></term>
<listitem>
<para>
The name of the specific index, table, or database to be
reindexed. Index and table names can be schema-qualified.
Presently, <command>REINDEX DATABASE</command> and <command>REINDEX SYSTEM</command>
can only reindex the current database. Their parameter is optional,
and it must match the current database's name.

<term><literal>CONCURRENTLY</literal></term>
<listitem>
<para>
When this option is used, <productname>PostgreSQL</productname> will rebuild the
index without taking any locks that prevent concurrent inserts,
updates, or deletes on the table; whereas a standard index rebuild
locks out writes (but not reads) on the table until it's done.
There are several caveats to be aware of when using this option
— see <xref linkend="sql-reindex-concurrently"/> below.
</para>
<para>
For temporary tables, <command>REINDEX</command> is always
non-concurrent, as no other session can access them, and
non-concurrent reindex is cheaper.
