Hi, i am using postgreSQL 7.2.1 on a redhat 7.2 (kernel 
2.4.9-31,glibc-2.2.4-24).

It seems that pg_dump -t "tablename" dumps correctly the sequence of a 
table's column,when the column is named after "id".

For example,

dynacom=# CREATE TABLE foo2 (fid serial NOT NULL UNIQUE PRIMARY KEY,id 
serial);

[postgres@pc216 ~]% pg_dump -t foo2 > foo2DUMP.sql 

[postgres@pc216 ~]% cat foo2DUMP.sql

        Constraint "foo2_pkey" Primary Key ("fid")
);

Any ideas??
