Hi @guewen,
some modules you are maintaining are being modified, check this out!

[sbidoul]

Yep, this should work.

[guewen]

Yes!

@PCatinean do you know who we should ping in the odoo.sh team to have an opinion on this approach?

[PCatinean]

Hi @sbidoul the only two people I know around this topic are @amigrave which gave the initial feedback on the advisory lock MR here #256 and @sts-odoo which also provided some feedback on the pg_application_name approach

[sbidoul]

@amigrave @sts-odoo so the TL;DR here is that we have one long lived connection to the database on which we take a session-level advisory lock and do a LISTEN. There is no long-lived transaction, so this should not impact replication.

I plan to deploy this on a odoo.sh dev env soon to see how it goes. I can PM you the details if you wish to monitor something.
