Hi, Thanks for your comment.
As you say, it would be difficult to unify the data types in all documents right now.
The patch I attached the other day unifies only the newly added columns in monitoring.sgml to "timestamp with time zone".
Regards,
Noriyoshi Shinoda

I agree that it would be good to make those consistently use timestamp with time zone for all columns of that type in the docs for pg_stat_all_tables.
More generally, it might be good if we did it for the entire docs:
doc $ git grep "<type>timestamptz</type>" | wc -l
17
doc $ git grep "<type>timestamp with time zone</type>" | wc -l
74
Clearly "timestamp with time zone" is much more commonly used.
The bar is probably set a bit higher for changing the longer-established ones, however.
