COPY generates CSV and similar formats, not .sql. only pg_dump, the
command line utility, outputs .SQL

try...

begin

FOR crtRow in
select account_id from backup_table WHERE migrated = 1
AND account_id in $1

LOOP

COPY

(SELECT * FROM gorfs.WBP_4868_backup_table_BLOBS WHERE
migrated = 1 AND account_id = crtRow.account_id)

TO '/var/lib/pgsql/gorfs_backup/' || crtRow.account_id || '.csv';

end loop;

return integer;

end

but you can't exactly return 'integer' if its a list of values, so I'm
not sure what it is you want to return from this function...
