# The value of EVENT_ID, END_EVENT_ID, NESTING_EVENT_TYPE, NESTING_EVENT_ID

# - there are IDLE events between top level queries,
# - there are no IDLE events between multi queries
# - STATEMENT starts right after the IDLE event
# - STAGE init starts right after
# - SOCKET events, when receiving the command,
#   are childrens of the STATEMENT select / STAGE init
