Is there a site equivalent to "caniuse.com" for all the different database features by product and version? If not, someone should build one. Often some DB would say they added feature X but what does that mean? Did they implement this in advance of other DBs or behind others?
The SQL spec is barely comprehensive of the SQL dialects found “in the wild”, let alone the entirely independent and much more interesting set of non-table managing/querying features databases provide.
It provides at best a baseline for comparison.. and a fairly shallow one at that
