Does the amount of memory allocate to work_mem get subtracted from
shared_buffers?
Example:
If work_mem is 1M and there are 10 connections and shared_buffers is
100M then would the total be 90 M left for shared_buffers?
Or does the amount of memory allocated for work_mem have nothing to do
with shared_buffers?
No, they're completely separate.
Note that a connection can use more than work_mem of memory. For
example, if you run a query with multiple Sort or hash-nodes, each such
node allocates up to work_mem of memory.
