chore(deps): bump postgres from 2.6.3 to 3.0.1 in /packages/athena_postgres

[dependabot]

Bumps postgres from 2.6.3 to 3.0.1.

Changelog

Sourced from postgres's changelog.

3.0.1

• Fix: do not allow execute after closing the Connection.
• Session.runTx() supports rolling back the transaction through TxSession.rollback() (otherwise any exception has the same effect, but callers need to catch it).
• Supporting more type aliases, including serial4, serial8, integer...
• Deprecated all of v2 API, legacy fallback will be removed in next minor version (3.1.0).

3.0.0

New features:

• New API (better names and consistency).
• New SQL parsing and configurable query substitutions.
• Integrated connection pooling.
• A somewhat-compatible legacy API support to help migrations (will be removed in 3.1.0).

BREAKING CHANGES

The package had a partial rewrite affecting public client API and internal behaviour, keeping most of the wire protocol handling from the old version.

Users of this package must rewrite and test their application when upgrading.

Notable breaking behaviour changes:

• Simple query protocol allows sending queries to the server without awaiting on the result. The new implementation queues these request on the client instead.
• Table name OIDs are not fetched or cached, this information from the result schema is absent, also causing mappedResultsQuery to be removed from the new API.
• Queries are not cached implicitly, explicit prepared statements can be used instead.
• interval values are returned as Interval type instead of Duration.
• A newly added UndecodedBytes instances are returned when the package does not know or has not implemented the appropriate type decoding yet. Previously these values were auto-encoded to String and if that failed the Uint8List were used.
• Types, fields and parameter names may have been renamed to be more consistent or more aligned with the Dart naming guides.

Legacy compatibility layer

package:postgres/legacy.dart provides a somewhat backwards-compatible API via the PostgreSQLConnection.withV3() constructor. Many features, including the ones mentioned above are missing and/or throw UnimplementedError when called.
