Found by driving the Postgres connection of the docker stack in a debug build.

• Timezone was always "—". pg_settings calls it TimeZone; the query listed lower-case names only. It now matches on lower(name).
• Memory settings showed raw numbers (shared_buffers 16384 is 16384 blocks of 8 kB). The query also reads unit and the card shows 128 MB, 4 MB, 4 GB (formatPgSetting, unit-tested).
• The table header hid Prev / Next / Refresh behind a sideways scroll at about 1000 px width, and the mouse wheel does not scroll sideways. The actions now wrap, as the Mongo documents toolbar does since fix(mongodb): the documents toolbar wraps in a narrow pane instead of overflowing #1825.

Not run locally; CI decides.

Seen, not changed: in the schema tree Extensions / Foreign data / Indexes / Triggers / Types show their chevron on the right, the other groups on the left.
