StringAgg

This class provides a PostgreSQL-specific implementation for aggregating strings into a single value using a specified delimiter. It includes a deprecation warning advising users to migrate to the standard database-agnostic aggregate implementation. The class automatically handles string-to-Value conversion for delimiters to ensure compatibility with future framework versions.
