PostgreSQL bytea columns (OID 17) are now decoded from hex format into Array[U8] val instead of being returned as raw hex strings. The decode validates the \x prefix and hex digit pairs at the _RowsBuilder boundary, producing an immutable byte array that consumers can use directly. Array[U8] val uses identity comparison by default in Pony, so Field.eq() implements element-by-element comparison for the new variant. Design: #118

PostgreSQL bytea columns (OID 17) are now decoded from hex format into
Array[U8] valinstead of being returned as raw hex strings. Only hex format is supported (the default since PostgreSQL 9.0).The
FieldDataTypesunion gainsArray[U8] valas a ninth variant. Existing code is unaffected — Pony's match is non-exhaustive, so code without a bytea arm continues to work.Field.eq()implements element-by-element comparison for byte arrays since Pony'sArrayuses identity comparison by default.Design: #118
