error loading data with copy - Mailing list pgsql-admin

I am trying to load data with the copy function,

*ham-existing=# \copy invst from '/home/fmwdba/transcoma' using
delimiters ','
\.
ERROR:  value too long for type character(7)
CONTEXT:  COPY invst, line 1, column stknum: "'0020338'"
ham-existing=#*

however, if I use the insert command and give the field names the data
will load.  Can anyone see what I am doing wrong?  I need to use the
copy function as I have a lot of data to laod.

This is how I created the table
CREATE TABLE Invst (
       STKNUM               CHAR(7) NOT NULL,

CREATE UNIQUE INDEX XPKInvst ON Invst

ALTER TABLE Invst
       ADD PRIMARY KEY (STKNUM);
