Hey, Alex!
I’ve created track 16 for your great charmed-postgresql snap.
BTW, does snap store has similar to charmhub capabilities
I suppose track creation for snaps should be available for creation in Web UI on snapcraft.io/$SNAP/releases page. Please let me know if you want to try this feature for some Data platform snaps and request guardrail for that purpose.
APIs for creating tracks should work for snaps as well, see the following discussion.
Thanks for your request and have a nice working week!
