Hello,
Is there a way with psql to get column output to be
"data1","data2",...,"datan"
I tried -F "," but that left off the first and last quote.
I can't seem to find a way in the man page.
Thanks,

Well, you can do it yourself kinda like this:
select '""||field1||'", "||field2||'" from sometable where yada.

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.

assuming you are trying to be compatible with CSV:
copy ( your_query_here ) to stdout with csv header ;

yeah -- that's the best way if you want actual csv, from psql you'd
probably want to do \copy:
postgres=# \copy (select 1, '"', 'ab,c') to stdout csv header;
?column?,?column?,?column?
1,"""","ab,c"
note that per csv rules columns are only required to be quoted to
protect from unambiguous parsing. also, double quotes in your field
will be escaped.
