A running homeserver exercises three shim capabilities beyond what the unit
tests reached; add them so it boots on the Rust backend end to end:
- `prepare_database` reads `db_conn.autocommit`; add a readable `autocommit`
getter to the shim `Connection` (and the adapter), mirroring psycopg2's
property.
- schema preparation runs multi-statement scripts via
`engine.execute_script_file` -> `cursor.executescript`; route
`LoggingTransaction.executescript` to the shim's multi-statement primitive
for the Rust backend (as it already does for sqlite), and expose
`executescript` on the DBAPI2 adapter cursor.
- store loading binds Python lists as Postgres arrays for `column = ANY($1)` /
`!= ALL($1)` (Synapse's `make_in_list_sql_clause`); add a `PgValue::Array`
variant that classifies a `list` and encodes it as an array of the element
column type, and accept array column types in `ToSql`.
With these, a homeserver boots on the Rust backend: it prepares the full schema
(176 tables), listens, `/health` returns OK, and DB-backed client endpoints
respond correctly.
Tested: array `to_sql` / classification and array-column `accepts` (Rust unit
tests); and, against a live Postgres, `= ANY($1)` list binding, adapter
`executescript`, and the `autocommit` getter. sqlite and psycopg2 homeserver
boots remain green.
