The following works for me (on 7.2b3).
 create table test( id serial, tid timestamp default now() ); select extract(week from tid) from test;


gram.y has extract_list:  extract_arg FROM a_expr

which appears to be in keeping with the sql99 def. part2-         <extract expression> ::= part2:              EXTRACT
<leftparen> <extract field> part2-                  FROM <extract source> <right paren>
 


I don't know if there was ever any other format for extract(), but
things look normal from here.


btw Marc, can you help me in getting archives of the various lists?

cheers. brent
