# -- Function: pgq.insert_event_raw(11)
# --
# -- Deprecated function, replaced by C code in pgq_lowlevel.so.
# --
# -- Actual event insertion. Used also by retry queue maintenance.
# --
# -- Parameters:
# -- queue_name - Name of the queue
# -- ev_id - Event ID. If NULL, will be taken from seq.
# -- ev_time - Event creation time.
# -- ev_owner - Subscription ID when retry event. If NULL, the event is for everybody.
# -- ev_retry - Retry count. NULL for first-time events.
# -- ev_type - user data
# -- ev_data - user data
# -- ev_extra1 - user data
# -- ev_extra2 - user data
# -- ev_extra3 - user data
# -- ev_extra4 - user data
