Not logging but if you re troubleshooting slow running queries in realtime  you can query the pg stat activity view to see which queries are active  the user connection they came from  when they started  etc  Eg    SELECT   FROM pg stat activity WHERE state    active   See the pg stat activity view docs

If you want to identify slow queries  than the method is to use log min duration statement setting  in postgresql conf or set per-database with ALTER DATABASE SET    When you logged the data  you can then use grep or some specialized tools - like pgFouine or my own analyzer - which lacks proper docs  but despite this - runs quite well

There s no history in the database itself but if you are using DataGrip data management tool then you can check the history thats your run in the datagrip

There s no history in the database itself  if you re using psql you can use   s  to see your command history there   You can get future queries or other types of operations into the log files by setting log statement in the postgresql conf file   What you probably want instead is log min duration statement  which if you set it to 0 will log all queries and their durations in the logs   That can be helpful once your apps goes live  if you set that to a higher value you ll only see the long running queries which can be helpful for optimization  you can run EXPLAIN ANALYZE on the queries you find there to figure out why they re slow    Another handy thing to know in this area is that if you run psql and tell it   timing   it will show how long every statement after that takes   So if you have a sql file that looks like this    timing select 1    You can run it with the right flags and see each statement interleaved with how long it took   Here s how and what the result looks like     psql -ef test sql  Timing is on  select 1    column   ----------         1  1 row   Time  1 196 ms   This is handy because you don t need to be database superuser to use it  unlike changing the config file  and it s easier to use if you re developing new code and want to test it out

FYI for those using the UI Navicat   You MUST set your preferences to utilize a file as to where to store the history   If this is blank your Navicat will be blank     PS  I have no affiliation with or in association to Navicat or it s affiliates  Just looking to help

You can use like  s   it will fetch you all command history of the terminal  to export it to file using  s filename

pgBadger is another option - also listed here  https   github com dhamaniasad awesome-postgres utilities  Requires some additional setup in advance to capture the necessary data in the postgres logs though  see the official website
