Unable to redeploy postgres service

Hello,

All this occurs in the environment dev of the project 65aff0db-6586-4be0-8420-b2e67ae4378d

I use the builtin Postgres 15 service https://github.com/railwayapp-templates/timescale-postgis-ssl/blob/main/Dockerfile.pg15-ts2.12

I made a typo running ALTER SYSTEM SET shared_preload_libraries = 'timescaledb, pg_stat_statements';

As result PG wasn't able to start anymore.

I tried to start PG skipping this config by setting the custom start command su -c "/usr/lib/postgresql/15/bin/postgres -c shared_preload_libraries=''" postgres

PG started but I couldn't connect with psql.
Happily ssh connection worked so I patched the content of /var/lib/postgresql/data/pgdata/[postgresql.auto](postgresql.auto).conf

I then tried to redeploy without start command and it never succeeded, even after waiting 35 minutes.
The only log I can get now being

Stopping Container
Stopping Container

Contrary to my original case where logs told me sharedpreloadlibraries was not loadable

And now, I can't ssh anymore:

Warning: Received unknown message type: ready
Error: Your application is not running or in a unexpected state.

I don't know what else to do but delete and recreate this service but i'd prefer to keep the config.

Thanks in advance

You can wipe that volume data and redeploy the service, just make sure to do a backup before that.
You will also lose the 'ALTER SYSTEM' settings that you've made

If I understand what you're saying… I don't think you can

Anyway I just realized we can only add one volume per service

After wiping the volum and started a redeploy, I got an error:

First it remigrated my legacy data as when I migrated to the bare metal offer
Then it failed with the message

Pre-deploy › Migrate volumes

(03:51)

Volume migration failed.

I'm now trying deleting the volume

Ok once the volume is deleted it starts fast BUT :

When a recreate the volume and redeploy it remigrates my old data <:mildpanic:804271964587819059>

It seems to be an issue related to old migration to the bare metal offer

You delete the volume, create a new one and there's the old data in it?

For now I need to go forward so I will simply use my service with no volume

jclaveau

but I will set it back once I'm not in a hurry anymore

Almost :

a recreate the volume
when redeploying it remigrates 1Gb of data

Looks solid now. However, did you remove the volume? There's no volume attached in dev. You should defs re-add it if you care about the data

Effectively, I deleted the volume as the only workaround to unlock my CI process but I'd like to get it back to save money (ram vs volume for our DB of several Gb and serverless mode for PRs and dev env).

I just recreated it:

(I wonder what is the 3rd change btw)

And... oO it works !

And the DB is empty, thank you very much !

Just a question. Will I have the same issue if I must redeploy my production db or is it fixed in any env ?

And another question : I let the fresh service with no data for more than an hour and it never got to sleep mode (serverless mode is enabled obviously). Is it normal or is there any configuration I miss?

Thanks in advance
