Patch isn't full, simple test (values are took from regression.diffs):
# create table tt (tv tsvector, tq tsquery);
# insert into tt values (E'''1 \\''2''', NULL);
# insert into tt values (E'''1 \\''2''3', NULL);
# insert into tt values ( E'''1 \\''2'' 3', NULL);
# insert into tt values ( E'''1 \\''2'' '' 3'' 4 ', NULL);
# insert into tt values ( NULL, E'''1 \\''2''');
# insert into tt values ( NULL, E'''1 \\''2''');
# insert into tt values ( NULL, E'1&(''2''&('' 4''&(\\|5 | ''6 \\'' !|&'')))');
# insert into tt values ( NULL, E'1&(''2''&('' 4''&(\\|5 | ''6 \\'' !|&'')))');

and try dump table and restore:
ERROR: syntax error
CONTEXT: COPY tt, line 5, column tq: "'1 ''2'"

PS I'm not subscribed to -patches, so I post to -hackers
