Wrong usage of pqMsg_Close message code?

Hi

I workin with protocol and reading related code.

I found in routine EndCommand one strange thing

void
EndCommand(const QueryCompletion *qc, CommandDest dest, bool
force_undecorated_output)
{
<-->char<--><-->completionTag[COMPLETION_TAG_BUFSIZE];
<-->Size<--><-->len;

<-->switch (dest)
<-->{
<--><-->case DestRemote:
<--><-->case DestRemoteExecute:
<--><-->case DestRemoteSimple:

<--><--><-->len = BuildQueryCompletionString(completionTag, qc,
<--><--><--><--><--><--><--><--><--><--><--> force_undecorated_output);
<--><--><-->pq_putmessage(PqMsg_Close, completionTag, len + 1);

<--><-->case DestNone:

There is message PqMsgClose, but this should be used from client side. Here
should be used PqMsg_CommandComplete instead?

Regards
