It would be great to add a logictest, probably in pkg/sql/logictest/testdata/alter_table. Add a test and
On the whole I'm good with this once it gets a test. I wonder if ultimately it'd be better if we had the appropriate tuple of values but I suppose that's neither here nor there and cockroach's ability to deal with tuple types is currently limited.

Thank you for taking a look @ajwerner. I have added a logic test for this.

Bad news, we don't support SHOW RANGES in all of our test configs, namely not in 3node-tenant. Can you create a new logictest file (split_at?) for this and put # LogicTest: !3node-tenant at the top. It should look just like
The output of the SPLIT AT command returns keys in the form `/Table/52/1/1` whereas the output of SHOW RANGES omits the prefix, of table id and index id, and displays keys as `/1`. This is a little confusing and making them consistent would make it easier to visually compare. This patch strips the prefix from the keys in the output of SPLIT AT. Release note (sql change): pretty column of SPLIT AT output was changed by stripping prefix. This makes it consistent with output from SHOW RANGES.

Ah - strange it didn't fail when I ran make testlogic locally. I've created a new file split_at and reverted changes to alter_table
