Description of Changes
Fixes #4825.
Reimplements the array SQL rendering fix from stale PR #3945 on current
master.The change adds a typed array serialization hook so SQL formatters can render arrays as one value instead of streaming each element independently.
spacetime sqlnow renders non-byte arrays with array delimiters, whilearray<u8>keeps the existing byte output. The PostgreSQL row encoder now emits primitive arrays as native PG arrays and nested/complex arrays as JSON array fields.API and ABI breaking changes
None.
Expected complexity level and risk
This touches shared SATS formatting, but the new hook preserves the previous default array serialization path and is only overridden by SQL-specific formatters.
