One frequent source of confusion are the different units that the parameters
in postgresql.conf use. shared_buffers is in 8 kB, work_mem is in 1 kB;
bgwriter_delay is in milliseconds, checkpoint_warning is in seconds.
Obviously, we can't change that without inconveniencing a lot of users.
I think it would be useful to allow units to be added to these settings, for
example
shared_buffers = 1000kB
checkpoint_warning = 30s
This would also allow
shared_buffers = 512MB
which is a bit cumbersome to calculate right now (you'd need = 65536).
I haven't thought yet how to parse or implement this, but would people find
this useful?
