hi
it was tested on 9.1 and 9.3. Interestingly - it worked without error in
8.2.
$ select to_tsquery('english', E'a\xe2\x80\x86a');
ERROR: syntax error in tsquery: "a a"
the 3-byte utf8 character is SIX-PER-EM SPACE (based on info from
http://www.fileformat.info/info/unicode/char/2006/index.htm)
Not sure what should happen with it, but generally I thought that
whitespace characters will get ignored (treated as separators) when
building tsquery.
It seems to work that way when building tsvector though:
$ select to_tsvector('english', E'a\xe2\x80\x86a');
to_tsvector
-------------
(1 row)
and for larger example:
$ select to_tsvector('english', E'depesz\xe2\x80\x86whatever');
to_tsvector
-----------------------
'depesz':1 'whatev':2
(1 row)
$ select to_tsquery('english', E'depesz\xe2\x80\x86whatever');
ERROR: syntax error in tsquery: "depesz whatever"
Best regards,
depesz
