Latency (query duration) — at least average. Better: histogram, percentiles
Connections (sessions) — stacked graph of session counts by state (first of all: active and idle-in-transaction; also interesting: idle, others) and how far the sum is from max_connection (+pool size for PgBouncer).
Longest transactions (max transaction age or top-n transactions by age), excluding autovacuum activity
Commits vs rollbacks — how many transactions are rolled back
