The following bug has been logged on the website:

Bug reference:      18419
Logged by:          Akshay Raut
Email address:      raut.akshay89@gmail.com
PostgreSQL version: Unsupported/Unknown
Operating system:   Windows 10
Description:        

We are using PostgreSQL 10.21 in which we are deleting a few records
periodically but we observed that the auto vacuum is not getting executed on
all the tables.

Due to this, we are not able to get the space held by the dead rows back to
the database and at some point in time our system runs out of space.

All the tables have adequate data and the deleted rows are also beyond the
scale factor and auto vacuum threshold.

Is this a known issue with PostgreSQL and is there any solution to resolve
this?

This issue has become very critical for us and any help will be highly
appreciated.

Thanks.

Regards,
Akshay Raut

If you were doing something like calling pg_stat_reset() then the
counters might be getting reset before they're high enough for
autovacuum to care.

Otherwise, perhaps autovacuum is running flat out due to badly tuned
autovacuum settings.

version 10 is out of support, so if there was some bug in that
version, we wouldn't fix it anyway.  v12 is the oldest supported
version, currently. https://www.postgresql.org/support/versioning/
