Bugreport: Creating tables w/ uppercase letters

I tried to create a table with uppercase letters by 'Create object'-'Table'.
The table was not found afterwards when I tried selecting from this table,
but the database was in the tree.
I also tried directly access the DB through psql, \d showed the table in
uppercase letters, select on this table did not work either.
Software:
pgAdmin II v1.3.60
PostgreSQL 7.2.1
