We have been developing the pg_bitemporal library for over six years. It started as a proof of concept; however, it has been used in the industrial setting at Braviant Holdings for the past four years. Responding to practical business needs, several functions not included in the original specs were added along with bitemporal integrity constraints support. Significant performance improvements were made. There is a definite business demand in the two-dimensional time support, and pg_bitemporal can cover a significant area of business needs. However, the usage of the functions is not always intuitive, and developers often need extensive onboarding before starting using this functionality. Responding to popular demand, we developed a quick tutorial that demonstrates the advantages of using bitemporal data representation vs. traditional tables following one simple test case.
