   There is also an option to grant privileges on all objects of the same

  <para>
   PostgreSQL grants default privileges on some types of objects to
   <literal>PUBLIC</literal>.  No privileges are granted to
   <literal>PUBLIC</literal> by default on
   tables,
   table columns,
   sequences,
   foreign data wrappers,
   foreign servers,
   large objects,
   schemas,
   or tablespaces.
   For other types of objects, the default privileges
   granted to <literal>PUBLIC</literal> are as follows:
   <literal>CONNECT</literal> and <literal>TEMPORARY</literal> (create
   temporary tables) privileges for databases;
   <literal>EXECUTE</literal> privilege for functions and procedures; and
   <literal>USAGE</literal> privilege for languages and data types
   (including domains).
   The object owner can, of course, <command>REVOKE</command>
   both default and  expressly granted privileges. (For maximum
   security, issue the <command>REVOKE</command> in the same transaction that
   creates the object; then there is no window in which another user
   can use the object.)
   Also, these initial default privilege settings can be changed using the
   <xref linkend="sql-alterdefaultprivileges"/>
   command.
  </para>

  <para>
   PostgreSQL 会把某些类型的对象上的默认特权授予给<literal>PUBLIC</literal>。默认在表、表列、序列、外部数据包装器、外部服务器、大对象、方案或表空间上不会有特权会被授予给<literal>PUBLIC</literal>。对于其他类型的对象，被授予给<literal>PUBLIC</literal>的默认特权是下面这些：数据库上的<literal>CONNECT</literal>以及<literal>TEMPORARY</literal>（创建临时表）；函数和过程上的<literal>EXECUTE</literal>特权；语言和数据类型（包括域）的<literal>USAGE</literal>特权。当然，对象拥有者可以<command>REVOKE</command>默认和专门授予的特权（为了最好的安全性，应该在创建该对象的同一个事务中发出<command>REVOKE</command>，这样其他用户就没有时间窗口使用该对象）。还有，这些初始的默认特权设置可以使用<xref linkend="sql-alterdefaultprivileges"/>命令修改。
