1. Native Temporal Table Support in PostgreSQL 19

"Wow. Incredible how this was not mentioned in the OP. I had done it with tcn triggers and adding '_archive' shadow tables manually with tcn … but doing it natively is gonna be, as per most PostgreSQL implementations, wonderful." — unfocso

2. AI‑Generated Writing & “Slop” Concerns

"It's not about style or formatting, people are tired of reading slop." — theappsecguy

3. Snowflake’s Moves & the Broader DB Landscape

"Snowflake laid off technical writers citing AI to replace them." — __s
