DQL supports ARRAYS_OVERLAP(), which tests whether two arrays have an
element in common, like the && operator of PostgreSQL, whose SQL DBAL
generates for every platform: the arrays are PostgreSQL arrays, or JSON
arrays on the other platforms, as stored by the json type.
SELECT a FROM Article a WHERE ARRAYS_OVERLAP(a.tags, :tags) = true
The function declares its return type, so that its result is hydrated
as a boolean, or NULL if an array is NULL. A custom function with the
same name keeps taking precedence, and the function fails with a
semantical error if the installed version of DBAL does not generate its
SQL.
The tests store the arrays with a type mapping them to TEXT[] on
PostgreSQL and to JSON on the other platforms.
It builds the ARRAYS_OVERLAP() function in the query builder.
