Problem/Motivation
New release 15.0 of Postgresql announced https://www.postgresql.org/about/news/postgresql-15-released-2526/
It brings the database inline with common MERGE expectations https://www.postgresql.org/docs/15/sql-merge.html
Core could adopt this feature by checking version string
Proposed resolution
Make sure core works on latest release and support native merge quesries
