v0.1.55

Security

• Docker images now use keyless cosign attestation @dkarter

Features

• Support execution of multi-statement queries sent via the simple protocol, e.g., SET statement_timeout TO 0; SELECT * FROM users;. Previously, this would error out. Limitation: we don't automatically start a transaction, so only one DML statement per query is allowed. @levkk
• Switch to our implementation of query normalization instead of using pg_query (only relevant if using the Enterprise edition) @sgrif @jkaczman

Performance

• Remove more unnecessary allocations @sgrif @meskill @jkaczman
• Don't pin small future in hot path (1% performance improvement or so) @ygxio

Bug fixes

• Avoid NoPrimary errors when primary election is delayed (role = "auto" mode) @meskill
• Preserve query case in admin commands before passing the string to the query parser @meskill
• Proxy shutdown was sometimes delayed by a race condition in the load balancer monitor @meskill
• Support parameter type casting in EXECUTE statements @murex971
• Don't run unnecessary SELECT query during sharding key update @jkaczman

Code quality

• Add query_parser_engine = "pg_query_protobuf" deprecation warning and remove the setting from usage @jkaczman
• Dead code removal @sgrif @meskill
• Use pub(crate) instead of pub to help with dead code analysis @sgrif
• Refactor the resharding task runner to use more types @meskill
• Move pool configuration into pgdog-config crate, for easier use in Enterprise code @meskill
• Fix flaky tests @jkaczman

New Contributors
