Consider following table creation command:

CREATE TABLE leaguescorehitter(id integer, playerid integer, scoreid
integer, value double, foreign key(id) references leagues(id), foreign
key(id, playerid) references playersinleague(id, playerid), foreign
key(scoreid) references scorehits(scoreid));

There are 3 foreign keys in this table for which there are 4 rows
displayed in my query as it should be:

1 for leagues(id)
1 for scorehits(scoreid)
2 for playersinleague(id,playerid) - 1 row per field

However what I would expect to see is:

[code]
ordinal_position      |    position_in_unique_constraint
      0                                      1
                           - this is for leagues(id)
      1                                      1
      1                                      2
                           - those 2 are for
playersinleague(id,playerid)
      2                                      1
                           - this is for scorehits(scoreid)
[/code]

Instead I got ordinal_positionv = position_in_unique_constraints and can't tell
which constraint is which, or more precisely, when the one ends and
second starts.

Hopefully this above will not be mangled and the spacing will be kept.

Thank you.
