> As you probably know, the group_concat function is SQLite (and MySQL) specific. In other databases (namely, PostgreSQL and SQL Server) the function is called string_agg. As of 3.44, SQLite also supports string_agg as an alias for group_concat(expr, sep) (...) Now the only black sheep is Oracle, where the poor function is called listagg.
Minor nitpick, but why not go all the way and add the Oracle syntax while they were at it? Is there a technical reason not to? (I've never used Oracle)
