Yes, Hydra Columnar and PostGIS get along just fine. We've not looked into any PostGIS-specific optimizations yet, but if users run into issues, we'll be happy to investigate.

based on https://github.com/HydrasDB/hydra/blob/main/columnar/src/bac...

the columnar "does not support gist, gin, spgist and brin indexes." :-(

and "gist" is important for spatial indexing : http://postgis.net/workshops/postgis-intro/indexing.html
