[SOLVED] Postgresql doesn't working with Citus and pg_stat

Postgresql doesn't working with Citus and pg_stat_statements at the same time

So, I built the PostgreSQL with citus extension in docker. I use the official documentation in citus, then I run this command in the terminal.

docker run -d --network citus-network --name citus_coordinator -p 5500:5432 -e POSTGRES_PASSWORD=mypassword citusdata/citus:11.1

Then Database successfully building. But I want to create the pg_stat_statements extension. I configuration the postgresql.conf file.

shared_preload_libraries = 'pg_stat_statements'
pg_stat_statements.track = all
pg_stat_statements.max = 10000
track_activity_query_size = 2048

Then I restarted the PostgreSQL container. Wrote the this query

SELECT * FROM pg_stat_statements;

in terminal. I saw this error

[55000] ERROR: pg_stat_statements must be loaded via shared_preload_libraries

I didn't understand, why the config file didn't see this extension, What was my mistake?

Solution

Solved
I am running the PostgreSQL container with postgres:latest image. Then I entered the container. So, I installed the citus from here into the container. Then installed apt-get install postgresql-contrib into the container.Next step, run create extension pg_stat_statements; And everything worked for me.
