Fixes Hub CI by bumping postgres to postgres 15 and node to 18.x

With the base image of ubuntu bumped in plumbing CI,
postgres was not getting installed, hence this patch
bumps the postgres version in Hub CI to as the new
version of ubuntu supports postgres 15 and above

Also in this patch node version is bumped to 18.x
