In the 2017 article we referenced to /r/postgresql which at the time had 5,100 members. It now has 25.5k. In the same time period as pgsql-general, it generated 175 messages among community members (20 posts, 155 responses). Similarly, we mentioned the Slack channel which at the time had 1100+ members. It now hosts 18.3k subscribers with similar activity of the subreddit. The People, Postgres, Data Discord, which did not exist in 2017, has 3,579 members and is quite active over its 28 channels. The listed collaboration venues don’t take into account the thousands of members among the international or associated (Brazil, Russia, TimescaleDB, Yugabyte, NeonDB, etc…) Postgres communities.
