• Allow encoding to be specified for connections. The setting will be used for all connection-related string conversions.
• Allow generic List type as substitution values in binary encoding (as long as the inner type matches).
• Refactor: replaced UTF8BackedString with generic encoding (not complete).
• Breaking change in package:postgres/messages.dart: default constructors made internal, parsing is done with more efficient reader.

• Improved (experimental) v3 implementation. #98 and #102 by simolus3.

• Added support for bigInt (int8) arrays. #41 by schultek.

• Updated to package:lints.
• Adding lowerCase values to AuthenticationScheme.
• Add new package:postgres/postgres_v3_experimental.dart library as a preview. It exposes the postgres client under a new API that will replace the current one in version 3.0.0 of this package. At the moment, the new library is experimental and not fully implemented. Until the actual 3.0.0 release, the new APIs might change without a breaking version.

  • Exposing column metadata through ColumnDescription.
  • row-level toTableColumnMap and toColumnMap
• PostgreSQLConnection and _TransactionProxy share the OID cache.
• default value for query(allowReuse = true) is set only in the implementation method.

Breaking behaviour

• Table OIDs are always resolved to table names (and not only with mapped queries).

• Add connection queue size

• Prevent the table name resolution of OIDs <= 0.

• Adds support for Dart 2

• Add full support for UUID columns.

• Preserve error stacktrace on various query or transaction errors.
• Read support for BYTEA columns.
