Release note: None
Before:
```
kena@kenax ~/cockroach % ./cockroach dump --insecure defaultdb
CREATE TABLE t (,
FAMILY "primary" (rowid)
);
Error: pq: at or near "from": syntax error
Failed running "dump"
```
After:
```
kena@kenax ~/cockroach % ./cockroach dump --insecure defaultdb
CREATE TABLE t (,
FAMILY "primary" (rowid)
);
Error: table "defaultdb.public.t" has no visible columns
HINT: To proceed with the dump, either omit this table from the list of tables to dump, drop the table, or add some visible columns.
--
See: cockroachdb#37768
Failed running "dump"
```
Release note (cli change): `cockroach dump` will now more clearly
refer to issue cockroachdb#37768 when it encounters a table with no visible
columns, which (currently) cannot be dumped successfully.

37199: storage: propagate errors from contentionQueue, catch stalls in roachtest r=nvanbenschoten a=nvanbenschoten Informs #36089. The PR is split into a series of commits. The first fixes part of a bug that was causing #36089 to fail (thanks to #36748) and the second improves the test to have a more obvious failure condition for this class of bug in the future. The third, fifth, and sixth clean up code. Finally, the fourth fixes another bug that could cause issues with #36089. Before the first commit, requests could get stuck repeatedly attempting to push a transaction only to repeatedly find that they themselves were already aborted. The error would not propagate up to the transaction coordinator and the request would get stuck. This commit fixes this behavior by correctly propagating errors observed by the `contentionQueue`. The second commit bumps the TxnLivenessThreshold for clusters running `kv/contention/nodes=4` to 10 minutes. This is sufficiently large such that if at any point a transaction is abandoned then all other transactions will begin waiting for it, throughput will drop to 0 for 10 straight minutes, and the test will fail to achieve its minimum QPS requirement. The fourth commit instructs pushers in the `txnwait.Queue` to inform all other pushers that are waiting for the same transaction when it observes an ABORTED transaction. I never saw this cause issues with #36089, but it seems very possible that it could given frequent tscache rotations. 38397: sql: deflake TestLogic//crdb_internal/max_retry_counter r=knz a=knz Fixes #38062. Release note: None 38654: exec: Handle NULLS in TopK sorter r=rohany a=rohany This commit fixes NULLs in the TopK sorter by avoiding use of the vec copy method, which has a bug. Instead, we add a set method to the vec comparator, and use the templatized comparator to perform the sets that the TopK sorter needs. To facilitate this, we add an UnsetNull method to the Nulls object. However, use of this method results in HasNull() maybe returning true even if the vector doesn't have nulls. This behavior already occurs when selection vectors are used. Based on discussions with @solongordon and @asubiotto, this behavior is OK, and future PR's will attempt to make this behavior better, and address the bugs within the Vec Copy method. 38725: cli/dump: more clearly inform the user upon tables with no visible columns r=knz a=knz Informs #37768. Informs #28948. This is coming up quite often on support, lately again on gitter and forum https://forum.cockroachlabs.com/t/error-while-dumping-core-backup/2901/3. This PR aims to lessen the burden on support and propose a clear "next action" for the user.
