Re: how many quotes?

I've found the problem, its not about the quotes, it's the way the assignment is made:
val:=SELECT nextval(\'usuarios_seq\'); <-WRONG
val:=nextval(\'usuarios_seq\'); <-RIGHT

SELECT INTO should work too.

Thanks everyone.

Two, or escape them: nextval(''usuarios_seq'')
or nextval(\'usuarios_seq\')
