Note: I did not include a test because the tz search path is hardcoded in the go std lib and our test images all have a valid database. If you can think of a test approach to overcome that, I'll take it. |

38197: cli: warn the user if the time zone database is unavailable r=knz a=knz Fixes #23828. (The part in that issue about the database not being up to date cannot be fixed using the Go standard library - this does not give access to the search path and the version number. A comprehensive fix needs to wait for #36864.) Release note (cli change): CockroachDB will now print out an error message and an informative hint if the time zone database is unusable. 38214: storage/tscache: save 4 bytes per encoded tscache value r=ajwerner a=nvanbenschoten `unsafe.Sizeof(hlc.Timestamp{})` was including XXX_sizecache, which was bloating the struct size even though it didn't have an effect on the encoded size of the timestamps, which we control in `encodeValue`. Even once we remove `XXX_sizecache` (#37706), it looks like `unsafe.Sizeof` will still include padding which we don't want to capture in the `encodedTsSize` constant, so this seems like the best approach.
