The various command-line utilities that have recently acquired a --sync-method option document it like this:
<term><option>--sync-method</option></term> But that is not how we document options which take an argument. We do it like this: <term><option>--pgdata=<replaceable>directory</replaceable></option></term> <term><option>--filenode=<replaceable>filenode</replaceable></option></term> etc. This one should be something like this: <term><option>--sync-method=<replaceable>method</replaceable></option></term> -- Robert Haas EDB: http://www.enterprisedb.com
