Looks like the backslash is interpreted as an escape character. Switch
on 'standard_conforming_strings' and probably turn off
'escape_string_warning'.

Don't know about the other one, I'm guessing you're supplying a
polygon or some other shape that is missing a closing segment (and
thus being a polyline effectively I guess). I've never worked with
shapes in postGIS though.
It could be caused by the above issue if parts of the shape definition
contain backslashes as well.

And finally, I know there is a limit on query size somewhere... You
might be hitting that with 16MB queries.
