```sql CREATE INDEX CONCURRENTLY IF NOT EXISTS "idx_a_foo_bar" ON "a" ((foo->>'bar')); ``` ```sh Err( CheckSQL( ParsingSQL( JsonParse( "invalid type: map, expected a string at line 1 column 225", ), ), ), ) ``` The double parentheses are required in `((foo->>'bar'))` but it looks like it's parsed as a `map` instead of a `string`.
