I'm curious how this could work... istm its fairly hard to predict a
reasonable value for max_fsm_pages before you ever create a single database
in your cluster... I could perhaps see this as becoming self tuning with an
integrated autovacuum, where autovacuum stores the values needed for this and
max_fsm_relations so that upon any restart these values get automatically
updated to a reasonable number. Even more ideal would be to not have them
require restart at all, but thats yet another level of magic...
