Subject: Update maintenance_work_mem/autovacuum_work_mem to reflect the 1GB limitation with VACUUM

Hi,

There's a well known limitation in the amount of memory that any
VACUUM process can use, capped at 1GB now. This is not reflected in
the documentation

https://www.postgresql.org/docs/current/runtime-config-resource.html

We should add a line that indicates that there is a limitation (that
should be IMO, backported to documentation of earlier versions as it
affects all supported versions), at least until such limitation is
lifted.

Kind regards, Martín
