Error with table that exists but postgres says it doesn't

I have a table I created and it shows up when I do the \dt from the psql prompt. But when I try to
do a select from it I get the following.

select * from jddattdata;
ERROR: cannot find attribute 1 of relation jddattdata

I haven't inserted any data yet. I tried to drop the table and I get an error also. Any way I can
clean some system table to help me fix this problem.
Thanks
