PostGIS is awesome! I use it quite extensively for the backend of my hobby project: https://cubetrek.com https://cubetrek.com It's basically a Strava-like webapp to manage activity data for running, hiking, biking etc. PostGIS makes it very easy to query tracks in a given bounding box, get matching activities to compare past performances on the same tracks etc. Also the GeoJSON conversion is very handy to integrate it with MapLibre GL JS on the front end.
