Обсуждение: How to find all current sequence IDs
Is there a way to get a list of all sequences, the schema it is used in, and the current sequence number in use?
The below SQL will give me the schema and sequences. It does not give me the current sequence number in use.
SELECT sequence_schema, sequence_name
FROM information_schema.sequences
ORDER BY sequence_name ;
Thanks,

Try something like
select relname, relnamespace::regnamespace, pg_sequence_last_value(oid)
from pg_class where relkind = 'S';

This has worked for me in the past:
select schemaname, sequencename, last_value
from pg_sequences;
Thank you,
