Problem on both versions
I want to collect postgresql slow queries plan, so I added to my postgresql.conf setting from documentation
session_preload_libraries = 'auto_explain'
auto_explain.log_min_duration = '5s'
in the end of config
But also we use
logging_collector = true
and if logging_collector is on, no explain in logs
If logging_collector commented, I can see plan of queries How can I use both options?
UPDATE: We had about 10 queries runs more than 5 seconds, but finally with grep we found only one output in log with explain instead of all plans How it could be only one record was logged? neither all plans, no no plans only one explain
