Re: WIP: System Versioned Temporal Table

Hi,

quick note: The documentation for this patch mentions:

 The <literal>starttime</literal> column
+    will be automatically added to the Primary Key of the table.

A quick tests shows that the endtime column is added instead:

postgres=# create table t1 ( a int primary key generated always as identity, b text ) with system versioning;
CREATE TABLE
postgres=# \d t1
                                      Table "public.t1"
  Column   |           Type           | Collation | Nullable |            Default            
-----------+--------------------------+-----------+----------+-------------------------------
 a         | integer                  |           | not null | generated always as identity
 b         | text                     |           |          | 
 starttime | timestamp with time zone |           | not null | generated always as row start
 endtime   | timestamp with time zone |           | not null | generated always as row end
Indexes:
    "t1_pkey" PRIMARY KEY, btree (a, endtime)
