Potentially Breaking Changes
Technically, two changes are breaking changes, but in practice these are extremely unlikely to break existing code.
- Conn.Begin and Conn.BeginTx return a Tx interface instead of the internal dbTx struct. This is necessary for the Conn.Begin method to signature as other methods that begin a transaction.
- Add Conn() to Tx interface. This is necessary to allow code using a Tx to access the *Conn (and pgconn.PgConn) on which the Tx is executing.
Fixes
- Releasing a busy connection closes the connection instead of returning an unusable connection to the pool
- Do not mutate config.Config.OnNotification in connect
4.0.1 (September 19, 2019)
- Fix statement cache cleanup.
- Corrected daterange OID.
- Fix Tx when committing or rolling back multiple times in certain cases.
- Improve documentation.
4.0.0 (September 14, 2019)
v4 is a major release with many significant changes some of which are breaking changes. The most significant are included below.
- Simplified establishing a connection with a connection string.
- All potentially blocking operations now require a context.Context. The non-context aware functions have been removed.
- OIDs are hard-coded for known types. This saves the query on connection.
- Context cancellations while network activity is in progress is now always fatal. Previously, it was sometimes recoverable. This led to increased complexity in pgx itself and in application code.
- Go modules are required.
- Errors are now implemented in the Go 1.13 style.
Rows
andTx
are now interfaces.- The connection pool as been decoupled from pgx and is now a separate, included package (github.com/jackc/pgx/v4/pgxpool).
- pgtype has been spun off to a separate package (github.com/jackc/pgtype).
- pgproto3 has been spun off to a separate package (github.com/jackc/pgproto3/v2).
- Logical replication support has been spun off to a separate package (github.com/jackc/pglogrepl).
- Lower level PostgreSQL functionality is now implemented in a separate package (github.com/jackc/pgconn).
- Tests are now configured with environment variables.
- Conn has an automatic statement cache by default.
- Batch interface has been simplified.
- QueryArgs has been removed.
