Hi Dave,
I am working on a feature to support INCLUDE clause of index in PG-11. As per the documentation https://www. postgresql.org/docs/11/static/ sql-createindex.html, columns listed in INCLUDE clause cannot also be present as index key columns. But I find different behaviour for below queries which are logically identical.
CREATE TABLE some_table
(
id serial primary key,
first_name character varying(45),
last_name character varying
)
CREATE INDEX ind1
ON public.some_table USING btree
(id)
INCLUDE(id)
TABLESPACE pg_default;
This query fails with error
ERROR: included columns must not intersect with key columns
CREATE INDEX ind1
ON public.some_table USING btree
(id asc nulls last)
INCLUDE(id)
TABLESPACE pg_default;
This query passes and index is created.
Kindly let me know if I am missing anything.
Thanks and Regards,
