In response to AI Rumman : > * What is the difference between shared_buffers and effective_cache_size? effective_cache_size: Sets the planner's assumption about the effective size of the disk cache that is available to a single query. This parameter has no effect on the size of shared memory allocated by PostgreSQL, nor does it reserve kernel disk cache; it is used only for estimation purposes. shared_buffers: Sets the amount of memory the database server uses for shared memory buffers. It's all copied from the doc, there are much more details about this parameters. Read the doc!
