How do request a list of available collections?

[tylere]

All of the collection-related endpoints require passing a collection_id value.
For example: /collections/{collection_id}/tilejson.json

How do you request a list of collections via titiler-pgstac? I would expect there would be something like:
/collections/list

@tylere I didn't added a /list endpoint because usually users will have access to a stac-fastapi application connected to the same pgstac database.

That's said, in eoapi, I've added a /collections endpoint https://github.com/developmentseed/eoAPI/blob/65ec346c31fc07ccec988baaea61629e5fcd7f10/runtime/eoapi/raster/eoapi/raster/app.py#L100-L110

@tylere in the latest release 1.3.0 I've added 2 debugs endpoints /collections and /collections/{collection_id}

titiler-pgstac/titiler/pgstac/main.py

Lines 113 to 133 in bb314ee

	@app.get("/collections", include_in_schema=False, tags=["DEBUG"])
	async def list_collections(request: Request):
	"""list collections."""
	with request.app.state.dbpool.connection() as conn:
	with conn.cursor(row_factory=dict_row) as cursor:
	cursor.execute("SELECT * FROM pgstac.all_collections();")
	r = cursor.fetchone()
	cols = r.get("all_collections", [])
	return [col["id"] for col in cols]
	@app.get("/collections/{collection_id}", include_in_schema=False, tags=["DEBUG"])
	async def get_collection(request: Request, collection_id: str = Path()):
	"""get collection."""
	with request.app.state.dbpool.connection() as conn:
	with conn.cursor(row_factory=dict_row) as cursor:
	cursor.execute(
	"SELECT * FROM get_collection(%s);",
	(collection_id,),
	)
	r = cursor.fetchone()
	return r.get("get_collection") or {}

which will be added when TITILER_PGSTAC_API_DEBUG=TRUE
