* Sequences

I have a strange dilemma. I've created a couple sequences I can't
remove.
Here is an example
I can
CREATE SEQUENCE "count1" ..........;
DROP SEQUENCE count1;
I can't
CREATE SEQUENCE "count1ListItems1" ..........;
DROP SEQUENCE count1ListItems1;
It states sequence xx does not exist.
I can \ds and it is there.
I'm using v7.2.3, is there a way to manually remove a sequence or best
yet why can't I remove a sequence that has only 16 chars?
Thanks,
Danny L. Morgan

Try:
DROP SEQUENCE "count1ListItems1";

TIP 2: you can get off all lists at once with the unregister command
(send "unregister YourEmailAddressHere" to majordomo@postgresql.org)

* smacks your hand for using uppercase letters *
Another big no no is not keeping your create sequences for sequences ( what
a pun ) in a file somewhere.
Otherwise you can't drop them because you don't remember what parameters
they took ( but you can always, as you say, look at system tables )
Check the \ds.
If not there try \dS, which leads you to do:
select * from pg_statio_all_sequences;
if it's still not there - give up - it's not there :-p

You can get the info from pg_class like so:
SELECT n.nspname
, c.relname
FROM pg_class c
, pg_namespace n
WHERE c.relnamespace = n.OID
AND c.relkind = 'S'
;

PostgreSQL 10.x
What query will give the name of all sequences in a database and the current or next value for each sequence?
This will give me everything except for the next value in the sequence.
SELECT * FROM information_schema.sequences;
Thanks,
Lance

Constructing dynamic SQL is always a bit tricky. Try define this
function:
---
CREATE OR REPLACE FUNCTION seqs_last_val()
RETURNS SETOF record
AS $$
DECLARE
_seqname varchar;
_r record;
BEGIN
SELECT INTO _r null::varchar AS seqname, -1::integer AS lastval;
FOR _seqname IN
SELECT sequence_name
FROM information_schema.sequences
WHERE sequence_schema = 'public'
LOOP
_r.seqname = _seqname;
EXECUTE format('SELECT last_value FROM %s', quote_ident(_seqname)) INTO _r.lastval;
RETURN NEXT _r;
END LOOP;
RETURN;
END
$$ LANGUAGE 'plpgsql';
---
Then run:
SELECT * FROM seqs_last_val() AS (seqname varchar, last_value integer);

If you have no permission or inclination to actually define something in
the database, here is a shell-based alternative:
---
# psql -Aqt -U evaristesys_adm -d evaristesys \
-c "SELECT sequence_name FROM information_schema.sequences WHERE sequence_schema = 'public' ORDER BY sequence_name;" \
| while read SEQ;
do
echo -n "$SEQ: ";
psql -Aqt -U evaristesys_adm -d evaristesys -c "SELECT last_value FROM $SEQ;";
done

Why not just do this:
select schemaname
, sequencename
, last_value
, increment_by
from pg_sequences
;
