FW: pgscript & select

It's not clear to me from the doc that pgscript doesn't work with select statements.
I'm trying to run

set @databasename='orbitz_hist_schema_hods' ;

select *
from pg_catalog.pg_namespace n1
where n1.nspname = '@databasename'
;

And when executed, I get no results in the data output tab.
Is this supposed to work?
