What is the scientifically correct way if using NULLs ?
Gilles Darold from the french company Dalibo, the ora2pg author, has blogged that the performance improvement given by the Svetlana's patch can be as high as 45%.
Henrietta will present a talk on Temporal and Bi-Temporal databases at the PostgresPrpo seminar at 2 Mar 2016.

The conference gathered about 100 people, including PostgreSQL developers, DBA and customers from all over the world.
Although the authors claim that gin is a powerful genie, the theme of drinks has eventually won: next-generation GIN has been called RUM.
Gin stands for Generalized Inverted Index and should be considered as a genie, not a drink.
Pg_probackup is a utility to manage backup and recovery of PostgreSQL database clusters. It is designed to perform periodic backups of the PostgreSQL instance that enable you to restore the server in case of a failure.
Functions for defining and using variables in client sessions.
The pg_pathman module provides optimized partitioning mechanism and functions to manage partitions.
An active monitoring agent for Postgres Pro. Based on zabbix, mamonsu provides an extensible cross-platform solution that can collect and visualize multiple Postgres Pro and system metrics.
Temporary tables are often being used. Their performance could be increased if they are removed from system catalog. Also it is attractive to allow using temporary tables on read-only standbys.
Business-critical applications require continuous monitoring and adjustment of query plans. The problem hardens due the fact that actual resources consumption by query execution could differ significantly with slight changes of the query plan cost. Thus, there is a permanent risk of bad plan selection and overall system performance degradation after collecting new statistics. DBAs want to protect themselves from this risk by freezing plans of particular most critical queries.
Current approach for execution is essentially a kind plan tree interpretation. JIT-compilation of queries means compilation of plan tree into binary. Such compilation could get rid of multiple levels of indirection therefore accelerating queries.
