Description: Select returns 0 rows for varchar field
Details:

I created a table with the following specs.
CREATE TABLE user_control
(
uci character varying(10) NOT NULL,
ucname character varying(20),
ucpwd character varying(10),
ucrole character varying(20),
CONSTRAINT user_control_pkey PRIMARY KEY (uci)
)
WITH (OIDS=FALSE);
ALTER TABLE user_control OWNER TO postgres;
GRANT ALL ON TABLE user_control TO postgres;

I have 2 records with the following details:
george,George,george,developer
1234567890,Temp,0,developer
When I try to retrieve this record with the following statement from a
ASP.Net (VB) app I get no rows returned.
Select * from user_control where uci = 'george'
However this statement works.
Select * from user_control where uci = '1234567890'
