Doesn't work for me,
cgh=> select chromosome || varchar(arm) as locus from experiments;
ERROR: parser: Syntax error at or near "arm"
neither does select chromosome || arm::varchar as locus from experiment;
but the solution is clearly in some form of casting!
I'm using PG 6.4, perhaps it's a version thing?
