Re: Allow auto_explain to log plans before queries are executed - Mailing list pgsql-hackers

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
