odd behavior when replicating
3commascapital opened this issue · comments
hi there, it seems that both the latest (2.4.2) as well as previous versions have some odd behaviors when streaming is setup. i am not sure if this is the right repo to be reporting this to, but here is an example of my logs after i run docker compose up CONTAINER_NAMES to start up my containers. This is after I have run docker compose down as well as docker volume rm $(docker volume ls -q)

i have been seeing a variety of behaviors when trying to get these to play nice with each other, however, it seems that regardless of whether or not i add the POSTGRESQL_SHARED_PRELOAD_LIBRARIES env i get the section about not having permission to create the extension timescaledb, but then the timescaledb always ends up running later anyway, which is kind of confusing.
also, if i don't start them together, on the second run, i am able to get the master to eventually be at a stable state, but no matter how many times i restart the slave, it always ends up exiting with code 1
This repository is for the Docker image, so if this is a general replication-related issue, you should either file a bug with PostgreSQL or if it is related to TimescaleDB, file a bug report in the main TimescaleDB repository.
