"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?

It does both.
