possible consistency problem

[Sebastian Böhm <seb(at)exse(dot)net>]

Hi,

some days ago I removed all foreign keys from the database to speed up  
an import.

Now I tried to create the keys again but it says:

ALTER TABLE ONLY xxxxxxx ADD CONSTRAINT yyyyyyyyy FOREIGN KEY (zzzzzz)  
REFERENCES aaaaaaa(bbbbbb) ON UPDATE CASCADE;
ERROR:  constraint "yyyyyyyyyyy" for relation "xxxxxxxx" already  
exists, but it's not in the schema

when I do:
alter table only payments drop constraint yyyyyyyyy;

it says :
ERROR: "cccccccccccc" is an index

note: the constraint in the error message in differed from the  
constraint in my drop statement !!! (I tried to drop the foreign key  
but in the error message it speaks of the primary key)

what is this ?


Thank you and Kind Regards
Sebastian
