Commit Message

[!] optimize `PostgresWriter.flush()` with custom `CopyFrom` iterator (#777)

Optimize `PostgresWriter.flush()` for better performance. It avoids
per-row JSON marshaling overhead.
Introduced `copyFromMeasurements` to batch process
`MeasurementEnvelopes` efficiently, grouping by metric and writing
directly to PostgreSQL using a streaming approach.
New approach reduces memory allocations and temporary objects, speeds up
`flush()` with lower GC pressure.
