[dependabot-preview]

Bumps pg_query from 1.1.0 to 2.0.3.

Changelog

Sourced from pg_query's changelog.

2.0.3 2021-04-05

• Update to libpg_query 13-2.0.4
  • Normalize: Fix handling of two subsequent DefElem elements (avoids crash)
  • Deparser: Fix crash in CopyStmt with HEADER or FREEZE inside WITH parens

2.0.2 2021-03-31

• COALESCE arguments are now included in #filter_columns
• Improve error message for protobuf parse failures
• Extconf: Fix object path regexp
  • This accidentally replaced .c in the wrong parts of the path in some cases, causing build failures
• Update to libpg_query 13-2.0.2
  • Fix ARM builds: Avoid dependency on cpuid.h header
  • Simplify deparser of TableLikeClause
  • Fix asprintf warnings by ensuring _GNU_SOURCE is set early enough

2.0.1 2021-03-18

• Fix gemspec to correctly reference include files
  • This would have shown as a build failure when using the published 2.0.0 gem

2.0.0 2021-03-18

• Update to PostgreSQL 13 parser
• Update to libpg_query v2, and new Protobuf-based format
  • WARNING: This is a breaking change if you are directly interacting with the parsetree (helpers like table and such still work the same way)
• Use actual Ruby classes for parser result, instead of decoded JSON
  • This is essentialy to enable easy and fast two-way communication with the C library, and as a bonus makes for a better interaction on the Ruby side, as we are handling actual objects instead of hashes and arrays.
• Use new deparser maintained directly in libpg_query
  • This replaces the complete Ruby deparser with a new, more complete deparser that is directly maintained in libpg_query. Further deparser improvements should be directly contributed to [libpg_query]
• Tables helper: Return more details through #tables_with_details method
  • This is renamed from the previously badly named #tables_with_types method. Note that this change should not affect the output of the primary tables helper.
• Replace on-demand libpg_query source download with bundled source code
  • Its unnecessary to download the source on-demand, and makes this more complex than it needs to be. Instead, introduce a new "update_source" rake task that can be called to refresh the source for a specified revision.
• Re-implement smart truncation without requiring a special node type
  • This ensures the #truncate method works with the new deparser, without
