pg_dump bug with default date

I use pg_dump to back up my database.  I recently changed one of my date
fields to have a default value as such:
    firstcontactdate date default current_date,

If I pg_dump the database and reload the CREATE statment for this table
fails.  pg_dump used this defintion:
    "firstcontactdate" "date" DEFAULT date 'current'::datetime + '0 sec'),
PSQL reports:
    ERROR:  parser: parse error at or near "'"

I can work around this problem by extracting the offending the table create
statement from the script, pre-creating the table with a corrected
definition and ignoring the error when the script tries to create the table.
I don't want to edit the script directly because it is 50MB and growing.
Fortunately the schema statements are all at the front so I can grab them
with "head -1000".

This is Postgres 6.4.0.  Is this a known problem?  Has it been fixed?
