Video of a conference talk about the temporal data concept—and the relationships between SQL standards and the implementation of bi-temporal data in PostgreSQL. This talk was delivered by Henrietta Dombrovskaya at Citus Con: An Event for Postgres 2023. In this talk, Henrietta also discusses how advanced temporal features, such as multiple time dimensions, are provided on top of standard basic features. Since 2011 the SQL standard has defined a set of features providing essential support for temporal data. These features include periods, row versioning, and syntax extensions for SQL commands. Some of these features already exist in recent releases of PostgreSQL. In addition, PostgreSQL provides several tools, such as GIST indexes, that are not explicitly related to temporal data but can make the implementation of temporal data efficient.
