Devin Clark: Storing Timezones in Postgres

1. Oktober 2020 - 2:00

Storing a user’s timezone in Postgres can be an interesting task in apps. Often, this is accomplished by generating a hardcoded list of every timezone in the backend (or worse the frontend JavaScript) and storing an item from that list in the database for each user.

Having watched Postgres grow in popularity over the years, I have seen my share of organizations with competing teams, some promoting Postgres, other dismissing it. I came up with this diagram (slide 23) which shows the three groups typically involved in deciding Postgres adoption. The groups are Managers, Administrators, and Developers.

30. September 2020 - 12:02
VACUUM and ANALYZE are the two most important PostgreSQL database maintenance operations.  A vacuum is used for recovering space occupied by “dead tuples” in a table.
