Moving from Oracle to Postgres, what should I know?
pg_wait_sampling together with pg_stat_statements gets you nearer to Oracle's ASH/AWR capabilities. PoWA can integrate that (and other interesting extensions) to generate some nice reports.

It might also help to use pgbadger or something similar to process your postgres logs and see whether some event is aligned with your outages.

SQL: 2023 Has Been Released
Interestingly, when a place does get to the point where the single instance has capacity issues (after upgrading to EPYC and lots of flash drives) then other non-obvious stuff shows up too.
For example, at one place just over a year ago they were well into this territory. One of weird problems for them was with pgBadger's memory usage (https://github.com/darold/pgbadger). That's written in perl, which doesn't seem to go garbage collection well. So even on a reporting node with a few hundred GB's of ram, it could take more than 24 hours to do a "monthly" reporting run.
There wasn't a solution in place at the time I left, so they're probably still having the issue... ;)

What are the top 3 most useful things that you have hosted over the years?
First of all I used a profiler (pgbadger and netdata) to figure out where the lags were coming from. I then tried the usual stuff (increasing shared_buffers, max_wal_size, min_wal_size from their ultra low defaults), but the biggest performance gain came from moving the database from eMMC to a mechanical hard drive :-D
