ok,. how about all the 'other' characters from us-ascii :
,.?!@#$%^&*()_+-=[]{}\|'"?><`~
these 'should' all be valid for the ltxtquery, ltree, and ltree[] types,
except maybe for . which is used as seperator (and maybe . should be
valid too, if prepended with a '\', just as you would with a regex to
make the next character a literal).
