Not sure if this is known or not, but apparently cursors names are not
appropriately case-lowered when dealing with functions that return cursors.
Using the example straight from the documentation at
http://developer.postgresql.org/docs/postgres/plpgsql-cursors.html:
This works:
BEGIN;
SELECT reffunc('funccursor');
FETCH ALL IN funccursor;
COMMIT;
But this doesn't work:
BEGIN;
SELECT reffunc('funcCursor');
FETCH ALL IN funcCursor;
COMMIT;
This 2nd one gives a warning in the log of:
WARNING: PerformPortalFetch: portal "funccursor" not found.
