I have a table that I have defined as:
CREATE TABLE test (
"id" SERIAL PRIMARY KEY,
"first_path" path NOT NULL,
"second_path" path NOT NULL
);
I am attempting to create a GiST index on the two “path” columns using:
CREATE INDEX "idx_test_first_path" ON test USING gist(first_path);
CREATE INDEX "idx_test_second_path" ON test USING gist(second_path);
I am getting this error:
Error : ERROR: data type path has no default operator class for access method "gist"
Is it that I am not allowed to create an index on the path data type or do I need to enable an extension for this to work? Thanks in advance for your help.
