Version 4.0

Version 4.0 - May 31 2024

This major release allow preloading pgtt in session_preload_libraries
and adds support to Windows operating system. Here is the complete list
of changes.

• Add port to Windows operating system. Thanks to Julien Rouhaud for
  the patch
• Allow preloading pgtt in session_preload_libraries. The module is now lazily
  loaded when it might be needed (after parse analysis, before executor
  startup and before utility statements execution), and all the code is simply
  bypassed if the underlying extension has not been created. Thanks to Julien
  Rouhaud for the patch.
• Fix first query execution after a LOAD command. If the extension is loaded
  with a plain LOAD command, the search_path will only be set during the next
  query execution. It means that the very first query executed after such a
  LOAD wouldn't see the global temporary tables. Thanks to Julien Rouhaud for
  the patch.
• Remove the relocation test, the extension is not relocatable anymore.
• Fix crash with RESET ALL. RESET ALL has a NULL "name" field, so we can't use
  strcmp in that case. Since the existing code is only interested in SET
  commands, just move up the check that the command is a VAR_SET_VALUE to
  ensure that we will have a GUC name. Thanks to Julien Rouhaud for the patch.
• Fix various minor whitespace and indent issues. Thanks to Julien Rouhaud for
  the patch.
• Add Julien Rouhaud in the authors and maintainers list.
