Hi,
that feature for dumping plans with auto explain is already available in
https://github.com/legrandlegrand/pg_stat_sql_plans
This is an hybrid extension combining auto_explain and pg_stat_statements,
adding a planid and tracking metrics even on error, ..., ...
With
pg_stat_sql_plans.track_planid = true
pg_stat_sql_plans.explain = true
--> it writes explain plan in log file after planning and only one time
per (queryid,planid)
then no need of sampling
and with
pg_stat_sql_plans.track = 'all'
--> function pgssp_backend_queryid(pid) retrieves (nested) queryid of a
stuck statement,
and permit to retrieve its plan (by its queryid) in logs.
Regards
PAscal
