Release notes

v5.11.0

This release adds direct PostgreSQL type scanning through database/sql on Go 1.27, improves compatibility with libpq connection strings and PostgreSQL date/time values, and includes further decoder hardening. See Changes for connection-string and date/time behavior changes that may affect existing applications.

Features

• stdlib: support Go 1.27's driver.RowsColumnScanner, allowing PostgreSQL types such as arrays and ranges to be scanned directly into Go values without pgtype.Map.SQLScanner. Existing database/sql scalar conversions and sql.Scanner behavior are preserved. The minimum supported Go version remains 1.25.
• Add Rows.TypeMap to expose the type map used to decode rows, including rows created by RowsFromResultReader that have no underlying Conn. Custom implementations of Rows, including mocks, must add this method.
• pgconn: add Config.MaxProtocolMessageBodyLen to configure the maximum incoming protocol message body size (carter-ya)
• pgconn: add ErrReadOnlyConnection, ErrReadWriteConnection, ErrPrimaryConnection, and ErrStandbyConnection sentinel errors for target_session_attrs validation, allowing callers to use errors.Is (Adrian-Stefan Mares)
• pgxpool: accept pool_ping_timeout in connection strings to configure Config.PingTimeout. The default is zero; zero and negative durations mean no timeout (1991santhu)

Changes

• Name-based row-to-struct mapping now matches explicit db tags case-insensitively, with exact matches taking precedence so tags can still distinguish quoted column names that differ only by case (AlisinaDevelo)

• pgconn: resolve the OS user account only when no user is supplied by the connection string, environment, or service file, avoiding unnecessary account lookups and crashes in some restricted container environments. Home-directory defaults for password, service, and TLS files remain available independently of the account lookup. On Unix these now use $HOME rather than the OS account's home directory (Mohamed MAACHE)

• pgtype: date, timestamp and timestamptz text values are now parsed and written by a hand-written parser and encoder for PostgreSQL's ISO date/time format instead of time.Parse and time.Format. Go's layout language cannot express a variable-width year or the BC era, which is the root of the bugs below. The text scan path is roughly 2.5x faster for timestamp and timestamptz. Bug fixes:

  • timestamp and timestamptz no longer silently move February 29 of a BC leap year to March 1 when encoding. time.Date(-4712, 2, 29, ...) was written as 4713-03-01 BC and is now written as 4713-02-29 BC. This affected ordinary four-digit BC years, not only extended-range ones. date was never affected.
  • timestamp and timestamptz can now scan BC leap days. 4713-02-29 BC previously failed with day out of range. date could already scan them.
  • Years past 9999 can now be scanned. 10000-01-02 03:04:05 previously failed to parse, so timestamp and timestamptz values at the high end of PostgreSQL's range were unreadable over the simple protocol and in any other text-format result.
  • time.Time arguments in the simple protocol now encode BC dates correctly, using the same timestamp encoder.
  • Fractional seconds beyond microsecond precision are rounded the way the server rounds them (round half to even, carrying into the rest of the value) instead of being kept at full precision. PostgreSQL never sends more than six fractional digits, so this only affects values from other sources.

  Behavior changes:

  • date now rejects impossible dates instead of normalizing them. 2024-02-30 returned 2024-03-01 and 2024-13-01 returned 2025-01-01; both are now errors. timestamp and timestamptz already rejected them.
  • All three types now reject values outside PostgreSQL's range for that type, in the binary format as well as the text format. PostgreSQL never sends out-of-range dates, so this only affects corrupt or hand-built input; the range
