<p>Thanks for your help.</p>
<p>I have found this to remove DDL locks and it works. I don't know
if it is a good way:</p>
<p>SELECT pg_terminate_backend(pid) FROM pg_stat_activity WHERE
datname = 'freeswitch';</p>
<p>ALTER ROLE $db_user SET bdr.permit_ddl_locking = false;</p>
<p>I will check to disable schema management features.<br>

If you are using shared db you should be disabling the features
for managing the schema. The issue is you will need to manually
maintain your schema. Almost always we manage schema it a way
that is backwards compatible so you can do staged upgrades if you
manually add to the tables.<br class="">
