Message-ID: <E1vGfb2-005Aqx-0D@gemulon.postgresql.org> (raw)
doc: Add section for temporal tables
This section introduces temporal tables, with a focus on Application
Time (which we support) and only a brief mention of System Time (which
we don't). It covers temporal primary keys, unique constraints, and
temporal foreign keys. We will document temporal update/delete and
periods as we add those features.
This commit also adds glossary entries for temporal table, application
time, and system time.
