+      If specified, the table is created as an unlogged table.  Data written
+      to unlogged tables is not written to the write-ahead log (see <xref
+      linkend="wal">), which makes them considerably faster than ordinary
+      tables.  However, they are not crash-safe: an unlogged table is
+      automatically truncated after a crash or unclean shutdown.  The contents
+      of an unlogged table are also not replicated to standby servers.
+      Any indexes created on an unlogged table are automatically unlogged as
+      well; however, unlogged <link linkend="GiST">GiST indexes</link> are
+      currently not supported and cannot be created on an unlogged table.
