Description
Description
Change the chainlink node package such that it uses postgresql-client-18, and thus PostgreSQL 18 is fully supported, including backups.
Motivation
Keep tech debt small by upgrading our fleet of PostgreSQL servers to 18. We prefer once-a-year upgrades by one major version to falling behind by two or more versions.
PostgreSQL 18 supports async IO
"Postgres 18 released with support for asynchronous input/output (Async I/O)
Previously, all read operations were blocking, but with this update they are no longer so, which provides a significant performance boost for applications with high read loads
In Postgres 18 this is enabled by default"
