You need to create a custom aggregate for this
CREATE AGGREGATE array_accum (
sfunc = array_append,
basetype = anyelement,
stype = anyarray,
initcond = '{}'
);
then use the field names in your query like this
select array_to_string(array_accum(field1 || '@' || field2),'#') as
field_alias from table_name
records will be seperated by '#'
hope this helps.
