find column OID types with information schema?

Is it possible to find out the OID types of the columns of a table
using the information schema?

I see that I can get the character names of the types using this query:

select * from information_schema.columns where table_name = 'my_table';

but I don't see a way to find the actual OID types of the columns. Is
that possible?

Thanks,
Whit
