Actually, what you got was a *textual* comparison between '1995' and
the timestamp converted to text, which makes even less sense.

FWIW, as of PG 8.3 you'll get an error:

regression=# select * from timestamp_tbl where d1 > 2007-10-02;
ERROR:  operator does not exist: timestamp without time zone > integer
LINE 1: select * from timestamp_tbl where d1 > 2007-10-02;                                            ^
HINT:  No operator matches the given name and argument type(s). You might need to add explicit type casts.

We've seen too many people get burnt by variants of this problem...
