textsearch.sgml neglected to mention that the MAXSTRPOS total-length limit applies to tsquery as well as tsvector. It also claims that there is a 32K limit on the total number of nodes in a tsquery, which is wrong. (I suspect that QueryOperator.left may once have been int16, which would give rise to such a limit. But it's uint32 now, so you'd hit the 1GB varlena limit well before overflowing that.) While at it, re-order the bullet points into an order that makes more sense, to me anyway.
