No specific reason. I think it's a good idea to put them. I'll update the code. |
I added the default values and the feedback from the K8S charm PR to efc7c8f. |

Issue
There is no way to provide custom configurations to the workload (PostgreSQL database).
Solution
Add to
patroni.yamlthe requested configurations with their default values.Expose the allowed configurations through charm config options (and add validators based on the allowed values).
max_connectionsandmax_prepared_transactionscan be changed only through the Patroni API, so they are changed in the charm code differently from the other configurations.Also, added a call to
time.sleep(10)to give some time to Patroni to reload the configurations before it's possible to know which ones need a database restart. Previously, sometimes a change inshared_bufferswouldn't trigger a restart.
