Release note (sql change): Arrays can now be imported in a CSV file
using the {} format, similar to COPY FROM. Importing array expressions
(e.g. ARRAY[1, 2, 3]) is still supported as well.

It is probably outside the scope of this change, but is there a grammar that a parser can be generated from?

you mean to avoid the fallback logic? it won't be that easy -- the difference between these two formats is that one is an expression (e.g. ARRAY[1, 2, 3 ...]) but the other is the format that arrays represented as string literals use (e.g. in {1, 2, 3 ... }::INT[]). The string literal format isn't (and i think shouldn't) be represented in our sql.y file, but it's handled in pkg/sql/sem/tree/parse_array.go
