Hi, all. I want to ask what type of index is better to create for bigint types. I have table with bigint (bigserial) primary key. What type is better to use for it? I tried btree and hash, but didn't notice any differences in execution time. For GiST and GIN there is a trouble that I must create operator class, so I limited myself to use btree or hash. But if it's better to use gist or gin, coment are welcome.
