Regarding storage paramaters, you mean ALTER TABLE x SET STORAGE...? Then no.
Only autovacuum settings are changed to be a bit more aggressive, vacuum
settings haven't been touched:
# select name,setting from pg_settings where source not in
('default','override') AND name LIKE '%vacuum%';
name | setting
--------------------------------+---------
autovacuum_max_workers | 4
autovacuum_naptime | 45
autovacuum_vacuum_cost_delay | 15
autovacuum_vacuum_cost_limit | 2000
autovacuum_vacuum_scale_factor | 0.1
autovacuum_vacuum_threshold | 75
