The infamous MSSQL "string or binary data will be truncated" error (fixed a while ago[0]), or the way either deals with unqualified access to columns which leads to surprises (e.g. in MSSQL subqueries or in Postgres's SECURITY DEFINER procedures).

Oracle seems to have more than most, IMO.
I have a journeyman data engineering level experience with each. Rare combo I guess, Data Scientist focus.
Also, I had to switch to DBeaver since Oracle SQL Developer made things worse with random crashes and freezes. Back when I used it, an easy way to freeze the editor was connecting to a DB via VPN and then suddenly disconnect. The connection gets stuck, parts of the UI get frozen and after a while the whole thing freezes.
MySQL/MariaDB and Postgres are better.
