pg_tileserv
pg_tileserv is a PostGIS-only tile server in Go. Strip away all the other requirements – it just has to take in HTTP tile requests and form and execute SQL. In a sincere act of flattery, the API and design look a lot like that of the Martin tile server.
This guide will walk you through how to install and use pg_tileserv for your spatial applications. The Usage section goes in-depth on how the service works. We also include some basic examples of web maps that render tiles from the pg_tileserv application.
