I've used Postgres for more than a decade and everytime I wade into the docs I feel the same way, I'm barely scratching the surface. It's so immensely powerful.

I love what LLMs are doing for me in PG's SQL. I discovered many features by having LLMs write them for me, often spot-on 100% on first prompt.

Since I know conceptually how RDBMSes work, I can ask vey specifically what I want. Also asking for feedback on schemas/queries really helped me. I use a lot more of PGs features now!
