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.
