Hi,

I knew that we create an entry in pg_type for every table we create,
what i didn't know is that we actually create 2 entries.

for example CREATE TABLE foo (i int); will create types foo and _foo.
so, any reason to create 2 entries?
anyway, what really kept my attention is that CREATE SEQUENCE also
create an entry in pg_type. there is any reason for that?
