Release Notes

1.5.5 (from changelog)

• Explicitly retype timespec fields to int64_t to fix compatibility with 32bit arches. #547
• Fix possible buffer overflows in PG::BinaryDecoder::CopyRow on 32 bit systems. #548
• Add binary Windows gems for Ruby 3.3.
• Update Windows fat binary gem to OpenSSL-3.2.1 and PostgreSQL-16.2.

1.5.4 (from changelog)

• Fix compiling the pg extension with MSVC 2022. #535
• Set PG::Connection's encoding even if setting client_encoding on connection startup fails. #541
• Don't set the server's client_encoding if it's unnecessary. #542 This is important for connection proxies, who disallow configuration settings.
• Update Windows fat binary gem to OpenSSL-3.1.2 and PostgreSQL-15.4.

1.5.3 (from changelog)

• Fix possible segfault when creating a new PG::Result with type map. #530
• Add category to deprecation warnings of Coder.new, so that they are suppressed for most users. #528

1.5.2 (from changelog)

• Fix regression in copy_data regarding binary format when using no coder. #527

1.5.1 (from changelog)

• Don't overwrite flags of timestamp coders. #524 Fixes a regression in rails: rails/rails#48049

1.5.0 (from changelog)

Enhancements:

• Better support for binary format:
  • Extend PG::Connection#copy_data to better support binary transfers #511
  • Add binary COPY encoder and decoder:
    • PG::BinaryEncoder::CopyRow
    • PG::BinaryDecoder::CopyRow
  • Add binary timestamp encoders:
    • PG::BinaryEncoder::TimestampUtc
    • PG::BinaryEncoder::TimestampLocal
    • PG::BinaryEncoder::Timestamp
  • Add PG::BinaryEncoder::Float4 and Float8
  • Add binary date type: #515
    • PG::BinaryEncoder::Date
    • PG::BinaryDecoder::Date
  • Add PG::Result#binary_tuples #511 It is useful for COPY and not deprecated in that context.
  • Add PG::TextEncoder::Bytea to BasicTypeRegistry #506
• Ractor support: #519
  • Pg is now fully compatible with Ractor introduced in Ruby-3.0 and doesn't use any global mutable state.
  • All type en/decoders and type maps are shareable between ractors if they are made frozen by Ractor.make_shareable.
  • Also frozen PG::Result and PG::Tuple objects can be shared.
  • All frozen objects (except PG::Connection) can still be used to do communication with the PostgreSQL server or to read retrieved data.
  • PG::Connection is not shareable and must be created within each Ractor to establish a dedicated connection.
• Use keyword arguments instead of hashes for Coder initialization and #to_h. #511
• Add PG::Result.res_status as a class method and extend Result#res_status to return the status of self. #508
• Reduce the number of files loaded at require 'pg' by using autoload. #513 Previously stdlib libraries date, json, ipaddr and bigdecimal were static dependencies, but now only socket is mandatory.
• Improve garbage collector performance by adding write barriers to all PG classes. #518 Now they can be promoted to the old generation, which means they only get marked on major GC.
• New method PG::Connection#check_socket to check the socket state. #521
• Mark many internal constants as private. #522
• Update Windows fat binary gem to OpenSSL-3.1.0.

Bugfixes:

• Move nfields-check of stream-methods after result status check #507 This ensures that the nfield-check doesn't hide errors like statement timeout.

Removed:

• Remove deprecated PG::BasicTypeRegistry.register_type and co. Part of #519
• Add deprecation warning about PG::Coder initialization per Hash argument. #514 It is recommended to use keyword arguments instead.
• The internal encoding cache was removed. #516 It shouldn't have a practical performance impact.

Repository:

• rake test tries to find PostgreSQL server commands by pg_config #503 So there's no need to set the PATH manuelly any longer.

1.4.5 (from changelog)

• Return the libpq default port when blank in conninfo. #492

• Add PG::DEF_PGPORT constant and use it in specs. #492

• Fix name resolution when empty or `nil` port is given.

• Update error codes to PostgreSQL-15.

• Update Windows fat binary gem to PostgreSQL-15.1 AND OpenSSL-1.1.1s.

1.4.4 (from changelog)

• Revert to let libpq do the host iteration while connecting. #485 Ensure that parameter `connect_timeout` is still respected.

• Handle multiple hosts in the connection string, where only one host has writable session. #476

• Add some useful information to PG::Connection#inspect. #487

• Support new pgresult_stream_any API in sequel_pg-1.17.0. #481

• Update Windows fat binary gem to PostgreSQL-14.5.

1.4.3 (from changelog)

• Avoid memory bloat possible in put_copy_data in pg-1.4.0 to 1.4.2. #473

• Use Encoding::BINARY for JOHAB, removing some useless code. #472

1.4.2 (from changelog)

Bugfixes:

• Properly handle empty host parameter when connecting. #471

• Update Windows fat binary gem to OpenSSL-1.1.1q.

1.4.1 (from changelog)

Bugfixes:

• Fix another ruby-2.7 keyword warning. #465

• Allow PG::Error to be created without arguments. #466

1.4.0 (from changelog)

Added:

• Add PG::Connection#hostaddr, present since PostgreSQL-12. #453

• Add PG::Connection.conninfo_parse to wrap PQconninfoParse. #453

Bugfixes:

• Try IPv6 and IPv4 addresses, if DNS resolves to both. #452

• Re-add block-call semantics to PG::Connection.new accidently removed in pg-1.3.0. #454

• Handle client error after all data consumed in #copy_data for output. #455

• Avoid spurious keyword argument warning on Ruby 2.7. #456

• Change connection setup to respect connect_timeout parameter. #459

• Fix indefinite hang in case of connection error on Windows #458

• Set connection attribute of PG::Error in various places where it was missing. #461

• Fix transaction leak on early break/return. #463

• Update Windows fat binary gem to OpenSSL-1.1.1o and PostgreSQL-14.4.

Enhancements:

• Don't flush at each put_copy_data call, but flush at get_result. #462
