Yes either an upper bound to which users can set their own values to.
Upper is somewhat easier but currently the system would only recognize a global constraint.
Does it? Even though my work_mem in postgresql.conf is 1MB, the user can alter itself to set its own work_mem to 1GB. Or did I interpret your statement wrongly?
Pg_settings currently has an upper bound column - though it is a view and that value cannot be changed that I know of.
I guess that upper bound column is more of the limit that is imposed by system which you can have for a parameter i.e. the system imposed limit or valid range if values for a parameter. I don't think one can update that.
But if it could I suspect that whatever catalog you would change to affect it would only cause a global change. There is no alter database, role, or postgresql way to change that value.
Oh ok... anyway of achieving that? There no EVENT trigger for "alter user"?
