Amazon RDS for PostgreSQL now supports h3-pg for geospatial indexing

Amazon Relational Database Service (RDS) for PostgreSQL now supports the h3-pg extension, which provides an API to H3, an open-source hexagonal, hierarchical geospatial indexing system. With this extension, you can perform different kinds of spatial analysis over large datasets, including efficient indexing and lookups, modeling flow through a grid, and applying machine learning models over your geospatial data stored in Amazon RDS for PostgreSQL.
