changing a definition in a dump file?

Hi all,
I think I inadvertently sent this to pg-admin...

Is it possible to change the definitions in the dump file to alter a
table.

this is from my  pgdump file:

CREATE TABLE "fc_client_info" (
   "acode" character varying(12),
   "cname" character varying(32)
);

If I change the file to read:

CREATE TABLE "fc_client_info" (
   "acode" character varying(12),
   "cname" character varying(128)
);

Can I drop the database and read in the altered pgdump file to effect the
change?

Thanks for your time.

Ted
