That's rather low. I suppose, you may safely say 200Mb here (check that you don't run into OS limits, they might need raising). You may also want to increase work_mem, but it depends on what the DB does, how many concurrent connections you have etc. pp. maintenance_work_mem may safely be set rather high - it speeds up vacuum etc. and is only used during such operations. Also look for effective_cache_size and max_fsm_pages. BTW: What version are you going to use?
