Sets the maximum number of workers that the system can support for
parallel operations. The default value is 8. When increasing or

Also, note that a setting for this value which is higher than

least a <literal>32MB</literal> share of the total
<varname>maintenance_work_mem</varname> budget. There must also be
a remaining <literal>32MB</literal> share for the leader process.
