Bug or feature in 7.3? - Mailing list pgsql-hackers

Hello.

Some example:
compile and install contrib/tsearch module
and now:
wow=# create table foo (bar txtidx);
CREATE
wow=# \d foo         Table "foo" Column |  Type  | Modifiers
--------+--------+----------- bar    | txtidx | not null


Why field 'bar' has modifier 'not null'?
