SQL plugin using go-libsql (CGO) instead of modernc.org/sqlite. Same schema, same config shape, same behaviour. Differences from the sqlite plugin: - Requires CGO_ENABLED=1 - No typed errors from go-libsql; IsDupEntryError matches extended codes 2067/1555 with a string fallback - DSN is file: path or :memory: only (no pragma params) - libsql ships with DQS=0, so double-quoted strings in DDL are identifiers. The visibility schema uses double-quoted JSON paths in generated columns — normalizeDQS rewrites them to single-quoted in CREATE/ALTER so the schema applies correctly. Config: pluginName "libsql", databaseName file path or :memory:.

Turso is basically SQLite under the hood, so this is a straightforward extension: same schema, same config shape, just swap in go-libsql instead of modernc.org/sqlite. When they ship multithreading it could be a drop-in performance boost for anyone using SQLite today.
Couple of fixes that came up:
"$.Foo"in generated columns and was failing. Plugin rewrites those to single-quoted when applying schema.Requires CGO. Config:
pluginName: "libsql",databaseNameis a file path or:memory:. Example inconfig/development-libsql.yaml.
