## 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` and `Tx` 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.
