Is it possible to have an SRF that can peek into the lastval data and
present it, and make no changes to our catalogs at all?
Or can't we use in the schema view something like:
CREATE VIEW sequences AS SELECT CAST(current_database() AS sql_identifier) AS sequence_catalog,
CAST(nc.nspnameAS sql_identifier) AS sequence_schema, CAST(c.relname AS sql_identifier) AS sequence_name,
(SELECT seq_info('sequence_name', 'max')) AS maximum_value, (SELECT seq_info('sequence_name', 'min')) AS
minimum_value, (SELECT seq_info('sequence_name', 'inc')) AS increment, (SELECT seq_info('sequence_name',
'cycle'))AS cycle_option FROM pg_namespace nc, pg_class c WHERE c.relnamespace = nc.oid AND c.relkind = 's';
