Next time, when you face this again, set log_min_duration_statement to
the value less that the age of hunging inserts and debug_print_parse,
debug_print_rewritten, debug_print_plan and debug_pretty_print to
'on'. It will allow you to log what is happening with these inserts
and what takes so many time.
