Possible values here are "auto" or "manual". If we set "auto" then the
233
charm will attempt to automatically tune all the performance paramaters
234
as below. If manual, then it will use the defaults below unless
235
overridden. "auto" gathers information about the node you're deployed
236
on and tries to make intelligent guesses about what tuning parameters
237
to set based on available RAM and CPU under the assumption that it's
238
the only significant service running on this node.

set. If manual, then it will use the defaults below unless set.

description: Shared buffers
253
The amount of memory the database server uses for shared memory
254
buffers. This string should be of the format '###MB'.
255
effective_cache_size:
259
Effective cache size is an estimate of how much memory is available for
260
disk caching within the database. (50% to 75% of system memory). This
261
string should be of the format '###MB'.
