It's EOL is 28 feb 2025 - starting from march 1st, we'll be paying more for it (extended support).

Should we contact PAH as well? It’s their stack (but not sure where it’s deployed), so it might be similar problem on their side.

We can refresh this one and move away from Postgres 13, which is ending support in February 2026. ;)
