<p>Yes I want node 1 remaining master after step 2.<br />Because I have custom method for resync DB after one node is detached and pgpool has no access to postgres through SSH.</p>
<p>During synchronization, client connections are not disconnected.</p>
<p> </p>
<p>Kind regards</p>

By the way do you want node 1 remaining master<br />> after step 2?<br />> <br />> Best regards,<br />> --<br />> Tatsuo Ishii<br />> SRA OSS, Inc.
