title: [openGauss]Please use "ALTER ROLE "user" PASSWORD 'password';" to set the password of the user before other operations
body: <p>The system prompts me to change the password each time the openGauss database is installed.
  To initialize the openGauss database, my steps as follows:</p>
  <p>step1:
  gs_initdb -D /data2/openGauss/install --nodename='datanode'</p>
  <p>step2：
  gaussdb -D /data2/openGauss/install --single_node -p 12300 &amp;</p>
  <p>step3:
  gsql -d postgres -p 12300 -r</p>
  <p>After the connection is successful, the system prompts me to change the password when run the SQL statement:</p>
  <p><strong>Please use &quot;ALTER ROLE &quot;user&quot; PASSWORD 'password';&quot; to set the password of the user before other operations!</strong></p>
  <p>My question is how to avoid changing the password after each installation.</p>
