Hi,

--------------
        if (recoveryTarget == RECOVERY_TARGET_XID)
                snprintf(buffer, sizeof(buffer),
                                 "%s%u\t%s\t%s transaction %u\n",
                                 (srcfd < 0) ? "" : "\n",
                                 parentTLI,
                                 xlogfname,
                                 recoveryStopAfter ? "after" : "before",
                                 recoveryStopXid);
        if (recoveryTarget == RECOVERY_TARGET_TIME)
                snprintf(buffer, sizeof(buffer),
                                 "%s%u\t%s\t%s %s\n",
                                 (srcfd < 0) ? "" : "\n",
                                 parentTLI,
                                 xlogfname,
                                 recoveryStopAfter ? "after" : "before",
                                 timestamptz_to_str(recoveryStopTime));
        else
                snprintf(buffer, sizeof(buffer),
                                 "%s%u\t%s\tno recovery target specified\n",
                                 (srcfd < 0) ? "" : "\n",
                                 parentTLI,
                                 xlogfname);

In writeTimeLineHistory, the result of the above first snprintf is always
overwritten by the following snprintf wrongly. I guess we forgot putting
"else" in the second "if" statement. I attached the very simple patch.

Since this bug was introduced in v9.0, the patch needs to be backported
to 9.0.
