This ensures that tables aren't dropped before <code>pg_dump</code> is able to drop them. A side effect of this is that any query which tries to take an <code>ACCESS EXCLUSIVE</code> lock on a table is be blocked by the <code>ACCESS SHARE</code> lock.</p><p>A number of timescale-internal processes require taking <code>ACCESS EXCLUSIVE</code> locks to ensure consistency of the data. The following is a non-exhaustive list of potentially affected operations:</p><ul><li>compress/decompress/recompress chunk</li><li>continuous aggregate refresh (before 2.12)</li><li>create hypertable with foreign keys, truncate hypertable</li><li>enable compression on hypertable</li><li>drop chunks</li></ul><p>The most likely impact of the above is that background jobs for retention policies, compression policies, and continuous aggregate refresh policies are blocked for the duration of the <code>pg_dump</code> command. This may have unintended consequences for your database performance.</p><div class="flex flex-wrap gap-x-2 gap-y-4 items-center [&amp;&gt;*]:my-0 mt-20"><h2 id="dumping-with-concurrency" class="max-w-full" data-label="Dumping with concurrency" tab-index="-1"><a href="#dumping-with-concurrency" class="![all:unset]"><span class="[overflow-wrap:break-word] cursor-pointer relative hover:before:bg-paperclip hover:before:absolute hover:before:-translate-x-6 hover:before:top-[0.5em] hover:before:-translate-y-1/2 hover:before:w-[17px] hover:before:h-[11px]">Dumping with concurrency</span></a></h2></div><p>When using the <code>pg_dump</code> directory format, it is possible to use concurrency to use multiple connections to the source database to dump data. This speeds up the dump process. Due to the fact that there are multiple connections, it is possible for <code>pg_dump</code> to end up in a deadlock situation. When it detects a deadlock it aborts the dump.</p><p>In principle, any query which takes an <code>ACCESS EXCLUSIVE</code> lock on a table causes such a deadlock. As mentioned above, some common operations which take an <code>ACCESS EXCLUSIVE</code> lock are:</p><ul><li>retention policies</li><li>compression policies</li><li>continuous aggregate refresh policies</li></ul><p>If you would like to use concurrency nonetheless, turn off all background jobs in the source database before running <code>pg_dump</code>, and turn them on once the dump is complete. If the dump procedure takes longer than the continuous aggregate refresh policy's window, you must manually refresh the continuous aggregate in the correct time range. For more information, consult the <a class="" href="/use-timescale/latest/continuous-aggregates/refresh-policies/">refresh policies documentation</a>.</p><p>To turn off the jobs:</p><div
