lgtm overall!
this is separate from this PR, but at some point i'd be interested in doing what i can to help the docs pages automatically get updated with new session variables. a table with descriptions gets auto-generated in the CRDB code base here: https://github.com/cockroachdb/cockroach/blob/master/docs/generated/sql/session_vars.md

| <span class="version-tag">New in v26.2:</span> `CREATE EXTENSION "fuzzystrmatch"` | ✓ | Common Extension | Provides PostgreSQL-compatible fuzzy string matching functions including `soundex()`, `difference()`, `levenshtein()`, `metaphone()`, [`dmetaphone()`]({% link {{ page.version.version }}/functions-and-operators.md %}#dmetaphone), [`dmetaphone_alt()`]({% link {{ page.version.version }}/functions-and-operators.md %}#dmetaphone_alt), and [`daitch_mokotoff()`]({% link {{ page.version.version }}/functions-and-operators.md %}#daitch_mokotoff). These functions are available without running `CREATE EXTENSION "fuzzystrmatch"`. CockroachDB does not have full support for `CREATE EXTENSION`.

technically, we also have the levenshtein_less_equal function. it's already on the page here though: https://www.cockroachlabs.com/docs/stable/functions-and-operators#fuzzy-string-matching-functions
so i'm not sure if it's necessary on this one
