Both. There's a bug there, but it's not the one you think.
psql seems to forget that it's got unmatched parentheses in the
buffer after executing a \? command. Watch the prompt:

regression=# (select
regression(# \?
... yadda yadda ...
regression-# 2;
ERROR: parser: parse error at or near ";"
regression=# (select
regression(# \?
... yadda yadda ...
regression-# 2);
?column?
----------
2
(1 row)

In the first example, it should not have thought that it had
a complete command after "2;".
