+ To specify a timeline ID in hexadecimal (for example, if extracted
+ from a WAL file name or history file), prefix it with a
+ <literal>0x</literal>. For instance, if the WAL file name is
+ <filename>00000011000000A10000004F</filename>, then the timeline ID is
+ <literal>0x11</literal> (or 17 decimal).
