PostgreSQL popularity is skyrocketing in the enterprise space. As this open source database continues to pull new users from expensive commercial database management systems like Oracle, DB2 and SQL Server, organizations are adopting new approaches and evolving their own to maintain the exceptional performance of their SQL deployments. We recently attended the PostgresConf event in San Jose to hear from the most active PostgreSQL user base on their database management strategies.

As the digital demands of the business continue to escalate, software delivery teams are under extraordinary pressure to deliver more work faster. Speed, however, counts for little if these teams are not delivering a high-quality product of value; rapid turnaround for a customer request is futile if the feature doesn’t work properly or meet their needs.

Summary There is a multitude of database metrics that we can collect and use to help us understand database and server resource consumption, as well as overall usage. This data can include hardware statistics, such as measures of CPU or memory consumed over time. We can also examine database metadata, including row counts, waits, and […].

There are places so remote, so harsh that humans can't safely explore them (for example, hundreds of miles below the earth, areas that experience extreme temperatures, or on other planets). These places might have important data that could help us better understand earth and its history, as well as life on other planets. But they usually have little to no internet connection, making the challenge of exploring environments inhospitable for humans seem even more impossible.
