for 9.1+ you can use built in format() function for a lot of fields:
select format('"%s", "%s", "%s", "%s"', procpid, usename, waiting,
query_start) from pg_stat_activity;
also with recent postgres you can use hstore to convert virtually any
query as such:
select '"' || array_to_string(avals(hstore(a)), '", "') || '"' from
pg_stat_activity a;
postgres=# select '"' || array_to_string(avals(hstore(q)), '", "') ||
'"' from (select 1 as a,2 as b,3 as c) q;
?column?
---------------
"1", "2", "3"
etc.
