Simple enough. The problem is that the tables you are importing had sequences associated with them. A sequence is
simplya counter that increments every time it is used. This allows, say, your primary key to be created as 1, then 2,
then3, and so on. There are two things you can do to solve this problem: 

1. Change the SQL that looks like this:

"mensajeid" int4 DEFAULT nextval('mensajes_mensajeid_seq'::text)

to this:

"mensajeid" SERIAL


2. Add create sequence statements to your SQL. They look like this:

CREATE SEQUENCE mensajes_mensajeid_seq START 101;

Change the number after "START" to be the largest number already in the table plus 1.

Beware that the first option may result in a collision of sequence numbers.

i.e. I import a record with a primary key of 1. Later I insert a record and the sequence is still set to 1. As a
result,the inserted record has a primary key of 1. The database rejects the inserted record due to a primary key
conflict.

Hope this helps,
Jerason
