Tighten up tsqueryrecv(). tsqueryrecv() accepted zero-length lexemes, which tsqueryin() doesn't. It also accepted phrase distance values larger than MAXENTRYPOS, which tsqueryin() doesn't. While neither of these omissions are very harmful in themselves, they do allow accepting tsquery values that will fail in a subsequent textual dump/reload.
Commit 23d9ad771 performed similar tightening of tsvectorrecv(), but I left off these changes at the time because they didn't seem to have security implications.
