[dependabot-preview]

Bumps pg from 1.1.4 to 1.2.1.

Changelog

Sourced from pg's changelog.

== v1.2.1 [2020-01-02] Michael Granger [email protected]

Enhancements:

• Added internal API for sequel_pg compatibility.

== v1.2.0 [2019-12-20] Michael Granger [email protected]

Repository:

• Our primary repository has been moved to Github https://github.com/ged/ruby-pg . Most of the issues from https://bitbucket.org/ged/ruby-pg have been migrated. #43

API enhancements:

• Add PG::Result#field_name_type= and siblings to allow symbols to be used as field names. #306
• Add new methods for error reporting:
  • PG::Connection#set_error_context_visibility
  • PG::Result#verbose_error_message
  • PG::Result#result_verbose_error_message (alias)
• Update errorcodes and error classes to PostgreSQL-12.0.
• New constants: PG_DIAG_SEVERITY_NONLOCALIZED, PQERRORS_SQLSTATE, PQSHOW_CONTEXT_NEVER, PQSHOW_CONTEXT_ERRORS, PQSHOW_CONTEXT_ALWAYS

Type cast enhancements:

• Add PG::TextEncoder::Record and PG::TextDecoder::Record for en/decoding of Composite Types. #258, #36
• Add PG::BasicTypeRegistry.register_coder to register instances instead of classes. This is useful to register parametrized en/decoders like PG::TextDecoder::Record .
• Add PG::BasicTypeMapForQueries#encode_array_as= to switch between various interpretations of ruby arrays.
• Add Time, Array, Array and Array encoders to PG::BasicTypeMapForQueries
• Exchange sprintf based float encoder by very fast own implementation with more natural format. #301
• Define encode and decode methods only in en/decoders that implement it, so that they can be queried by respond_to? .
• Improve PG::TypeMapByColumn#inspect
• Accept Integer and Float as input to TextEncoder::Numeric . #310

Other enhancements:

• Allocate the data part and the ruby object of PG::Result in one step, so that we don't need to check for valid data. This removes PG::Result.allocate and PG::Result.new, which were callable but without any practical use. #42
• Make use of PQresultMemorySize() of PostgreSQL-12 and fall back to our internal estimator.
• Improve performance of PG::Result#stream_each_tuple .
• Store client encoding in data part of PG::Connection and PG::Result objects, so that we no longer use ruby's internal encoding bits. #280
• Update Windows fat binary gem to OpenSSL-1.1.1d and PostgreSQL-12.1.
• Add support for TruffleRuby. It is regulary tested as part of our CI.
• Enable +frozen_string_literal+ in all pg's ruby files

Bugfixes:

• Update the license in gemspec to "BSD-2-Clause". It was incorrectly labeled "BSD-3-Clause". #40
• Respect PG::Coder#flags in PG::Coder#to_h.
• Fix PG::Result memsize reporting after #clear.
• Release field names to GC on PG::Result#clear.
• Fix double free in PG::Result#stream_each_tuple when an exception is raised in the block.
