Vacuum not working

Hi guys,

I have following problem: I use POWA to collect performance data from 20 postgresql servers. Vaccum doesn't clean the largest table after POWA database is growing large. Here are data taken at 19:27:

                  relname                   | last_vacuum | last_autovacuum  |     n_tup      |    dead_tup    |  av_threshold  | expect_av

--------------------------------------------+-------------+------------------+----------------+----------------+----------------+-----------

powa_all_relations_history_current         |             | 2020-10-08 18:24 |    162,254,592 |     82,045,219 |        162,280 | *

Can you please advise me how to tune poasgresql vacuum parameters to get this table cleaned? All other tables are vacummed as expected.

Best regards!
