Unable to reflect postgresql parameter changes after executing playbook

[kumarashish071092]

I have added below entries in vars/main.yml file :

log_checkpoints = on
log_connections = on
log_disconnections =on
log_lock_waits=0
log_temp_files=0
log_autovacuum_min_duration=0
log_error_verbosity=default
log_statement=off
log_min_duration_statement=10
log_line_prefix = '%t [%p]: db=%d,user=%u,app=%a,client=%h '

After executing the playing the changes were not reflected in the database.

I have also added "pending_restart: false" and "pending_restart: true" and made modifications in the config_pgcluster.yml as well .

the query "select * from pg_settings where pending_restart is true;" is also giving null data.

what am I missing here?

@vitabaks any update here? I am trying few options but still it is not reflecting.

[vitabaks]

Please provide all information for analysis:

1. the variables file main.yml
2. the ansible playbook execution log
3. the result of the patronictl show-config command

[vitabaks]

To change the Postgres configuration in a cluster using automation:

1. change the parameters in the postgresql_parameters variable. You can also specify the pending_restart: true variable so that Postgres is automatically restarted if a parameter change requires a restart.
2. run config_pgcluster.yml playbook to apply changes.

[vitabaks]

@kumarashish071092 Judging by ansible.log, you ran deploy_pgcluster.yml, but you need config_pgcluster.yml to manage the cluster parameters after deployment.

[vitabaks]

@kumarashish071092 Is the problem still relevant?

[sapisuper]

@vitabaks the problem still relevant, I also facing this problem.

[sapisuper]

please see the attachment, I will provided main.yml, ansible execution log and result from patronictl show-config

issue-postgresql_cluster.zip

[vitabaks]

@sapisuper Have you tried this on version 1.9.0 according to the instructions?

[vitabaks]

according to the ansible log, I see that the task "Update conf file" has been completed

TASK [../../roles/patroni/config : Update conf file "/etc/patroni/patroni.yml"] ***********************************************************************************************************************************************************
changed: [172.16.11.99]
changed: [172.16.11.25]
changed: [172.16.12.156]

but I do not see the task "Update postgresql parameters in DCS". Since no changes have been made to the DCS so you don't see the changes. Code here

Please attach an archive of the entire postgresql_cluster directory so that I can analyze all the changes you have made.

@vitabaks hi Vita, thanks for you feedback I will check later.
