Huge delay to finish even having all the records inserted

Hi,

I'm inserting 14 millions records from a text file using the Postgre COPY
command.

After waiting five days I've realized that all the records seems to be
already inserted,

but the process is still running!!

I don't know if there's any internal postgresql process that impose that I
have to wait even having the records shown in a SELECT query...

I don't know if it's safe to cancel the process right now.

Here's the activity query result (I've cut the columns into lines):

postgres=# SELECT * from pg_stat_activity ;
