Unless the change is *urgent*, just make it, and it is noticed automatically, before too long. Changes in databases such LDAP, Postgres and MySQL are noticed right away. Changes in hash, btree, cdb and other indexed tables are also prompt, because Postfix processes automatically restart after a database file change after completing the handling of the current requent (connection, ...). Changes in regexp, pcre or texthash tables are (IIRC) not noticed until a later periodic restart after $max_use requests or $max_idle inactivity. -- Viktor.
