Range of caracters

Hello,

I have a doubt about a query using a range of caracters. Example:

Data Table

Inicial ------------- Final
9C2HB02107R008000 9C2HB02107R008200
FAIXA1 FAIXA100

I´m doing the following query:

SELECT recallfxchassi.* FROM recallfxchassi
LEFT JOIN recall ON recallfxchassi.idrecall = recall.id WHERE
('FAIXA2' BETWEEN chassiinicial AND chassifinal);

This is not returning anything. I believe that is because it´s check´s caracter by caracter and 2 is bigger than 1. But in a real situation I will need that return something (FAIXA2 is between FAIXA1 and FAIXA100).

Does anyone knows if exists some way or command in PostgreSQL that could solve this "problem" ?

Thanks.
