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.
