Subject: maintenance_work_mem  is it per instance or per database??

Hello all,

Is the parameter maintenance_work_mem is per database or per instance??

And while exploring the configuration parameters I'm assuming that the sum
of values(default values) for the parameters maintenance_work_mem(64MB),
work_mem(4MB),temp_buffers(8MB), wal_buffers(4MB) will be equal to the value
of shared buffers(128MB).

But the total corresponds to 80MB where is the remaining part of shared
buffers(48MB) used?? I have read like clog buffers don't have any explicit
parameter to be set, it is tuned automatically by database engine

So will that remaining will be used by the client requests??

Please clarify me. Thanks in advance!!

Regards,
Pavan
