I'm trying to define the following exclusion-constraint
alter table my_table add EXCLUDE USING gist (is_default WITH =, daterange(valid_from, valid_to, '[)') WITH &&) WHERE (is_default = true);
But it fails with:
ERROR: data type boolean has no default operator class for access method "gist"
HINT: You must specify an operator class for the index or define a default operator class for the data type.
I have the btree_gist extension installed.
So, my question is; Is there an existing operator-class I can install to make this work, and if not - how do I make it?
I know I can change is_default to INTEGER and use 1 and 0, but I'd really like to use boolean for this.
Thanks.
