The current solution is naive and does not support complex queries. It need to be reworked with a query parser such as jsqlparser or calcite to cover cases involving subqueries, GROUP BY, HAVING, LIMIT, and ORDER BY clauses in user provided queries.

Fix performance issue on PG Tile Store (#909, #912)
51b638a 
The query optimizer of Postgres 15 is not able to push conditions down when using sub-queries. Therefore, we now append the spatial conditions to the sub-query. The unit tests have been adapted accordingly. A more robust solution involving a query parser will be devised (#913) in the future to account for more complex queries (GROUP BY, HAVING, etc.).
