Subject: Analyze on Children Tables
Content-Type: text/plain; charset=gb18030; format=flowed
Content-Transfer-Encoding: 7bit

I'm on pg 9.1.3. When I analyze verbose on parent table, I see all the
children are analyzed in the log. But I found the last analyzed time of
children tables are not changed. So my question is, after I analyzed the
parent, should I re-analyze children tables?
