Hi Pavel,
> There is message PqMsgClose, but this should be used from client side. Here should be used PqMsg_CommandComplete
instead?
It seems so. This change was introduced in f4b54e1ed98 [1]:
```
--- a/src/backend/tcop/dest.c
+++ b/src/backend/tcop/dest.c
@@ -176,7 +176,7 @@ EndCommand(const QueryCompletion *qc, CommandDest
dest, bool force_undecorated_o
len = BuildQueryCompletionString(completionTag, qc,
force_undecorated_output);
- pq_putmessage('C', completionTag, len + 1);
+ pq_putmessage(PqMsg_Close, completionTag, len + 1);
case DestNone:
case DestDebug
```
It should have been PqMsg_CommandComplete.
