Summary:
The test PgAnalyzeReadTimeTest.AnalyzeMultipleTables relies on compaction finishing in 10s. However, compaction takes around 15s on dev server in TSAN mode.

I0313 21:19:08.751065 3641125 pg_analyze_read_time-test.cc:125] Compaction done!
```

This is ~14s, over 10s and leads to a snapshot too old error.
