Обсуждение: GiN indexes
“Currently, only the B-tree, GiST and GIN index types support multicolumn indexes.”
What does this mean exactly if I’m trying to create a multicolumn GIN index? Does this mean the index can contain one or more tsvector type fields only, or can I combine tsvector type field with other type fields in the index, such as a timestamp column?
