databases/ruby-pg: update to 1.1.3

== v1.1.3 [2018-09-06] Michael Granger <ged@FaerieMUD.org>

- Revert opimization that was sometimes causing EBADF in rb_wait_for_single_fd().

== v1.1.2 [2018-08-28] Michael Granger <ged@FaerieMUD.org>

- Don't generate aliases for JOHAB encoding.
  This avoids linking to deprecated/private function rb_enc(db)_alias().

== v1.1.1 [2018-08-27] Michael Granger <ged@FaerieMUD.org>

- Reduce deprecation warnings to only one message per deprecation.

== v1.1.0 [2018-08-24] Michael Granger <ged@FaerieMUD.org>

Deprecated (disable warnings per PG_SKIP_DEPRECATION_WARNING=1):
- Forwarding conn.exec to conn.exec_params is deprecated.
- Forwarding conn.exec_params to conn.exec is deprecated.
- Forwarding conn.async_exec to conn.async_exec_params.
- Forwarding conn.send_query to conn.send_query_params is deprecated.
- Forwarding conn.async_exec_params to conn.async_exec is deprecated.

PG::Connection enhancements:
- Provide PG::Connection#sync_* and PG::Connection#async_* query methods for explicit calling syncronous or asynchronous libpq API.
- Make PG::Connection#exec and siblings switchable between sync and async API per PG::Connection.async_api= and change the default to async flavors.
- Add async flavors of exec_params, prepare, exec_prepared, describe_prepared and describe_portal.
  They are identical to their syncronous counterpart, but make use of PostgreSQL's async API.
- Replace `rb_thread_fd_select()` by faster `rb_wait_for_single_fd()` in `conn.block` and `conn.async_exec` .
- Add PG::Connection#discard_results .
- Raise an ArgumentError for strings containing zero bytes by #escape, #escape_literal, #escape_identifier, #quote_ident and PG::TextEncoder::Identifier. These methods previously truncated strings.

Result retrieval enhancements:
- Add PG::Result#tuple_values to retrieve all field values of a row as array.
- Add PG::Tuple, PG::Result#tuple and PG::Result#stream_each_tuple .
  PG::Tuple offers a way to lazy cast result values.
- Estimate PG::Result size allocated by libpq and notify the garbage collector about it when running on Ruby-2.4 or newer.
- Make the estimated PG::Result size available to ObjectSpace.memsize_of(result) .

Type cast enhancements:
- Replace Ruby code by a faster C implementation of the SimpleDecoder's timestamp decode functions. github #20
- Interpret years with up to 7 digists and BC dates by timestamp decoder.
- Add text timestamp decoders for UTC vs. local timezone variations.
- Add text timestamp encoders for UTC timezone.
- Add decoders for binary timestamps: PG::BinaryDecoder::Timestamp and variations.
- Add PG::Coder#flags accessor to allow modifications of de- respectively encoder behaviour.
- Add a flag to raise TypeError for invalid input values to PG::TextDecoder::Array .
- Add a text decoder for inet/cidr written in C.
- Add a numeric decoder written in C.
- Ensure input text is zero terminated for text format in PG::Coder#decode .

Source code enhancements:
- Fix headers and permission bits of various repository files.

Bugfixes:
- Properly decode array with prepended dimensions. #272
  For now dimension decorations are ignored, but a correct Array is returned.
- Array-Decoder: Avoid leaking memory when an Exception is raised while parsing. Fixes #279
