Using two tables (postgreSql) to validate users

[Daniel Bojczuk]

Hi again...

I have a doubt: Is it possible to use two tables to check the users? I
need to do something like this... Freeradius checks if the user is valid
on the table 1, if it returns true the user is validated, but if the
return is false, freeradius checks the table 2, trying to validate the
user once again.

Is it possible?

Thanks,

Daniel
