Description

In the GTFS spec, the agency_id field in agency.txt is conditionally required:

  • Required when the dataset contains data for multiple transit agencies.
  • Recommended otherwise.

Current behaviour: Single-agency feeds without agency_id are rejected, because agency_id is enforced as a primary key in lib/agency.js.

https://github.com/public-transport/gtfs-via-postgres/blob/cd8fe457fe1583b97aaee5e9fcfae1771ca4c938/lib/agency.js#L6C2-L6C29

Expected behaviour: Single-agency feeds without agency_id should be accepted as per the GTFS spec.

Contributor guide

Research direction
Examine the primary key enforcement in lib/agency.js and adjust it to allow missing agency id for single agency feeds, following the GTFS spec condition.
