schema question

[Isaac Vetter <ivetter(at)math(dot)purdue(dot)edu>]

Hi All;

I'm much more of a web developer than dba, that's why I'm asking this of 
the novice list.

I've got a database in postgresql 7.4 with 111 tables.

I recently created the 111th table and I cannot create foreign key 
constraints.

Postgresql acts like the new table is in a different schema that the 
referenced table. Additionally, if I go back to a previously created 
table and try to rename a foreign key column (by dropping and adding) I 
cannot recreate the foreign key. The error that I get is that the 
referenced schema does not exist:

ERROR:  schema "table2" does not exist

If I specify the schema name on both tablenames, when adding the constraint:

alter table public.table1 add foreign key(table2_id) references 
public.table2.id;

I get this error:
ERROR:  cross-database references are not implemented


I know very little about postgresql's schema's. Am I doing things 
correctly? I've never had this kind of a problem before. Postgresql has 
treated me very well. Has anyone else experienced similar problems?

p.s. I know that I need to upgrade to v8. That's not possible right now.
