GRANT question

I am a user, len, and I own a schema, called fec. cs386 is another user.

In psql 8.3.1 (server 8.3.3) I ran a shell script that included these statements

**BEGIN EXCERPTS FROM SHELL SCRIPT

-- I seem to need to say this in every shell script, it doesn't 'stick'
SET search_path TO fec;

....

SELECT fecid, c.commid, occup, month, amount
INTO indivcl
FROM indiv i, comm c WHERE i.commid = c.commid and i.zip = '97223' and
year = 2008
and month < 5 and c.assoccand in ('P80003338', 'P80002801' ,
'S6OR00094' , 'S8OR00207')
;

...

GRANT SELECT ON candcl, commcl, indivcl, pascl TO cs386;

** END EXCERPTS FROM SHELL SCRIPT

When the user cs386 logs in via the GUI interface phpPgAdmin, s/he
cannot SELECT from indivcl. Then len logs in via that GUI interface,
issues the statement
GRANT SELECT ON indivcl TO cs386;
and then cs386 can access indivcl .

What is wrong? Why did the effect of the "GRANT SELECT ..." statement
in the shell script not persist? I'd appreciate any advice.
