Hi, I use GetODBCerrors function (which I found somewhere in internet) to
return the errors I get back from PostgreSQL.
Hope  this help

dim m_Dbh As ADODB.Connection
dim m_LastError as String
...
Run query
...
If m_Dbh.Errors.Count > 0 Then  m_LastError = GetODBCerrors


Function GetODBCerrors() As String
    On Error GoTo GetODBCerrors_ErrHandler
    GetODBCerrors = ""
    Dim objError As ADODB.Error
    Dim strError As String
    If m_Dbh.Errors.Count > 0 Then
        For Each objError In m_Dbh.Errors
            strError = strError & "Error #" & objError.Number & " " &
objError.Description & vbCrLf & "NativeError: " _
                    & objError.NativeError & vbCrLf & "SQLState: " &
objError.SQLState & vbCrLf & "Reported by: " & _
                    objError.Source & vbCrLf & "Help file: " &
objError.HelpFile & vbCrLf & "Help Context ID: " & _
                    objError.HelpContext
        Next
        GetODBCerrors = strError
    End If
    Exit Function

GetODBCerrors_ErrHandler:
    GetODBCerrors = Err.Number & " " & Err.Source & " " & Err.Description
End Function
