Hello! From all that I can tell, it is not possible using a btree_gist index as a primary key. If so, why not? I have a table with this gist index which truly ought to be its primary key. as_of_date is of range date type:
EXCLUDE USING gist (id WITH =, as_of_date WITH &&)
Any direction here would be much appreciated.
Right now, I am forced to create a redundant btree index UNIQUE, btree (id, lower(as_of_date)) in order to have a primary key on the table.
Thanks!
