I wish to create this data structure but GIN does not currently support an array of ENUM. Is intarray() a good place to look into adding ENUM support or is there already an operator class for working supports enums that I simply don't see at the moment.
This is being done as an alternative to a very large number of boolean columns which are rarely true (under 1%).
CREATE TYPE feature AS ENUM ('item1', 'item2', 'item3');
CREATE TABLE test (id serial PRIMARY KEY, features feature[]);
CREATE INDEX test_features_idx ON test USING GIN (features, id);
ERROR: data type feature[] has no default operator class for access method "gin"
HINT: You must specify an operator class for the index or define a default operator class for the data type.
Thanks in advance,
Rod
