Unreleased

Fixes

  • Oid underlying type changed to uint32, previously it was incorrectly int32 (Manni Wood)

Features

  • Add xid type support (Manni Wood)
  • Add cid type support (Manni Wood)
  • Add tid type support (Manni Wood)
  • Add "char" type support (Manni Wood)
  • Add NullOid type (Manni Wood)
  • Add json/jsonb binary support to allow use with CopyTo
  • Add named error ErrAcquireTimeout (Alexander Staubo)

Compatibility

  • jsonb now defaults to binary format. This means passing a []byte to a jsonb column will no longer work.

2.9.0 (August 26, 2016)

Fixes

  • Fix *ConnPool.Deallocate() not deleting prepared statement from map
  • Fix stdlib not logging unprepared query SQL (Krzysztof Dryś)
  • Fix Rows.Values() with varchar binary format
  • Concurrent ConnPool.Acquire calls with Dialer timeouts now timeout in the expected amount of time (Konstantin Dzreev)

Features

  • Add CopyTo
  • Add PrepareEx
  • Add basic record to []interface{} decoding
  • Encode and decode between all Go and PostgreSQL integer types with bounds checking
  • Decode inet/cidr to net.IP
  • Encode/decode [][]byte to/from bytea[]
  • Encode/decode named types whose underlying types are string, int, int8, int16, int32, int64, uint, uint8, uint16, uint32, uint64

Performance

  • Substantial reduction in memory allocations

2.8.1 (March 24, 2016)

Features

  • Scan accepts nil argument to ignore a column

Fixes

  • Fix compilation on 32-bit architecture
  • Fix Tx.status not being set on error on Commit
  • Fix Listen/Unlisten with special characters

2.8.0 (March 18, 2016)

Fixes

  • Fix unrecognized commit failure
  • Fix msgReader.rxMsg bug when msgReader already has error
  • Go float64 can no longer be encoded to a PostgreSQL float4
  • Fix connection corruption when query with error is closed early

Features

This release adds multiple extension points helpful when wrapping pgx with custom application behavior. pgx can now use custom types designed for the standard database/sql package such as github.com/shopspring/decimal.

  • Add *Tx.AfterClose() hook
  • Add *Tx.Conn()
  • Add *Tx.Status()
  • Add *Tx.Err()
  • Add *Rows.AfterClose() hook
  • Add *Rows.Conn()
  • Add *Conn.SetLogger() to allow changing logger
  • Add *Conn.SetLogLevel() to allow changing log level
  • Add ConnPool.Reset method
  • Add support for database/sql.Scanner and database/sql/driver.Valuer interfaces
  • Rows.Scan errors now include which argument caused error
  • Add Encode() to allow custom Encoders to reuse internal encoding functionality
  • Add Decode() to allow customer Decoders to reuse internal decoding functionality
  • Add ConnPool.Prepare method
  • Add ConnPool.Deallocate method
  • Add Scan to uint32 and uint64 (utrack)
  • Add encode and decode to []uint16, []uint32, and []uint64 (Max Musatov)

Performance

  • []byte skips encoding/decoding

2.7.1 (October 26, 2015)

  • Disable SSL renegotiation

2.7.0 (October 16, 2015)

  • Add RuntimeParams to ConnConfig
  • ParseURI extracts RuntimeParams
  • ParseDSN extracts RuntimeParams
  • ParseEnvLibpq extracts PGAPPNAME
  • Prepare is now idempotent
  • Rows.Values now supports oid type
  • ConnPool.Release automatically unlistens connections (Joseph Glanville)
  • Add trace log level
  • Add more efficient log leveling
  • Retry automatically on ConnPool.Begin (Joseph Glanville)
  • Encode from net.IP to inet and cidr
  • Generalize encoding pointer to string to any PostgreSQL type
  • Add UUID encoding from pointer to string (Joseph Glanville)
  • Add null mapping to pointer to pointer (Jonathan Rudenberg)
  • Add JSON and JSONB type support (Joseph Glanville)

2.6.0 (September 3, 2015)

  • Add inet and cidr type support
  • Add binary decoding to TimestampOid in stdlib driver (Samuel Stauffer)
  • Add support for specifying sslmode in connection strings (Rick Snyder)
