This removes the pgrust entry (added in #1163, updated to v0.4-preview in #2106) from the benchmark. The results it reports are produced by machinery written specifically for the 43 ClickBench queries, and its hot runs replay cached answers of the previous run. Both violate the rules: query result caches and caches near the end of the pipeline must be disabled, and the entry is tagged tuned: no while it is tuned for these exact queries.

Everything below was verified against the published v0.4-preview release binary (pgrust.com/downloads/v0.4-preview/, the one install downloads) and the public v0.3 source (github.com/malisper/pgrust). The v0.4-preview source is not published; the binary identifies itself as pgrust 0.3-beta.
