Log Message:
databases/ruby-pg: update to 1.2.2

== v1.2.2 [2020-01-06] Michael Granger <ged@FaerieMUD.org>

Enhancements:

- Add a binary gem for Ruby 2.7.

== v1.2.1 [2020-01-02] Michael Granger <ged@FaerieMUD.org>

Enhancements:

- Added internal API for sequel_pg compatibility.

== v1.2.0 [2019-12-20] Michael Granger <ged@FaerieMUD.org>

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<Time>, Array<BigDecimal> and Array<IPAddr> \ 
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.
- Fix PG::Result#stream_each_tuple to deliver typemapped values.
- Fix encoding of Array<unknown> with PG::BasicTypeMapForQueries

Deprecated:
- Add a deprecation warning to PG::Connection#socket .

Removed:
- Remove PG::Connection#guess_result_memsize= which was temporary added in pg-1.1.
- Remove PG::Result.allocate and PG::Result.new (see enhancements).
- Remove support of tainted objects. #307
- Remove support of ruby-2.0 and 2.1. Minimum is ruby-2.2 now.

Documentation:
- Update description of connection params. See PG::Connection.new
- Link many method descriptions to corresponding libpq's documentation.
- Update sync_* and async_* query method descriptions and document the aliases.
  The primary documentation is now at the async_* methods which are the default \ 
since pg-1.1.
- Fix documentation of many constants
