Ruben Fiszel 7bdfc0ea06 fix: avoid named prepared statements in datatable/PG executor (#8988)
Always send queries as unnamed prepared statements (query_typed_raw)
when arg types resolve via otyp_to_pg_type. This eliminates the
intermittent "prepared statement \"sN\" does not exist" error reported
on datatable scripts whose Postgres connection sits behind a
transaction-mode pooler (PgBouncer/Supabase pooler/RDS Proxy), where
prepare and execute can land on different backend connections.

The previous code only used the unnamed-statement path when the parser
detected at least one explicitly typed arg; datatable-generated SQL
with bare $1/$2 (relying on inline ::cast hints) fell back to
prepare + query_raw and accumulated named statements (s0, s1, ...,
s882, ...) on the cached connection, which the pooler then dropped.
