> Last year I proposed an enhancement allowing to use the implicit db schema to ease life of end-user, unfortunately it seems that it affects the startup time of the product when the tables contain a lot of rows. Indeed the query can take several seconds to return a result.
> The idea of this task would be to optimize this query for all supported databases in order to avoid this drawback.
