Version 4.4

Version 4.4 - July 02 2025

This is a maintenance release to fix a search_path error when using pg_dump.

• Fix pg_dump error with invalid search_path. pg_dump set search_path to
  empty string, appending the pgtt schema in this case make it fail.
• Update regression test expected output file related to search_path test.

Version 4.3

Version 4.3 - June 09 2025

This is a quick maintenance release to fix an issue introduced in latest
release.

• Drop extension before running tests on search_path.
• Fix invalid search_path error. When pgtt isn't preloaded and pg_catalog
  is the last element in search_path, results in error message "invalid
  value for parameter 'search_path'" due to invalid list syntax. Thanks
  to Japin Li for the patch.

Version 4.2

Version 4.2 - June 08 2025

This is a maintenance release to fix issues reported by users since latest
release and especially a search_path modification issue.

• Preserve pg_catalog at end of search path if it is the case to allow
  pg_catalog overloaded function to be executed.
• Add regression test on search_path forcing.
• Preserve $user and other elements in search_path. Thanks to Japin Li
  for the patch.
• Remove the LOAD command from documentation. Thanks to Li Jianping for the
  patch.
• Fix session_preload_libraries documentation for non-superusers. Thanks
  to Japin Li for the patch.
• Resolve a warning regarding incompatible pointer types. Thanks to Li
  Jianping for the patch.

Version 4.1

Version 4.1 - March 18 2025

This is a maintenance release to fix issues reported by users since latest
release.

• Use query instead of \d to list indexes in regression tests.
• Fix wrong complain about temporary table created and active when a
  regular temporary table is created with (LIKE ... INCLUDING INDEXES).
  Thanks to Benjamin Wirth for the report.
• Remove documentation for non-superuser configuration. Thanks to Julien
  Rouhaud for the patch.
• Fix config in README. The concrete path to the shared library is not
  needed in postgresql.conf. Thanks to Simon Martin for the patch.
• Install docs to a non-generic name, add a symlink to README.md that is
  referenced in DOCS. Thanks to Christoph Berg for the patch.
• Add vaccum pg_class + pg_sleep(1) after each drop table in regression
  tests to wait that the temporary table is really removed.
• Add missing PGDLLEXPORT tags on callback functions, those are needed on
  windows. Thanks to Julien Rouhaud for the patch.

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.
