Michael Paquier d46aa32ea5 Fix build inconsistency due to the generation of wait-event code The build generates four files based on the wait event contents stored in wait_event_names.txt: - wait_event_types.h - pgstat_wait_event.c - wait_event_funcs_data.c - wait_event_types.sgml The SGML file is generated as part of a documentation build, with its data stored in doc/src/sgml/ for meson and configure. The three others are handled differently for meson and configure: - In configure, all the files are created in src/backend/utils/activity/. A link to wait_event_types.h is created in src/include/utils/. - In meson, all the files are created in src/include/utils/. The two C files, pgstat_wait_event.c and wait_event_funcs_data.c, are then included in respectively wait_event.c and wait_event_funcs.c, without the "utils/" path. For configure, this does not present a problem. For meson, this has to be combined with a trick in src/backend/utils/activity/meson.build, where include_directories needs to point to include/utils/ to make the inclusion of the C files work properly, causing builds to pull in PostgreSQL headers rather than system headers in some build paths, as src/include/utils/ would take priority. In order to fix this issue, this commit reworks the way the C/H files are generated, becoming consistent with guc_tables.inc.c: - For meson, basically nothing changes. The files are still generated in src/include/utils/. The trick with include_directories is removed. - For configure, the files are now generated in src/backend/utils/, with links in src/include/utils/ pointing to the ones in src/backend/. This requires extra rules in src/backend/utils/activity/Makefile so as a make command in this sub-directory is able to work. - The three files now fall under header-stamp, which is actually simpler as guc_tables.inc.c does the same. - wait_event_funcs_data.c and pgstat_wait_event.c are now included with "utils/" in their path. This problem has not been an issue in the buildfarm; it has been noted with AIX and a conflict with float.h. This issue could, however, create conflicts in the buildfarm depending on the environment with unexpected headers pulled in, so this fix is backpatched down to where the generation of the wait-event files has been introduced. While on it, this commit simplifies wait_event_names.txt regarding the paths of the files generated, to mention just the names of the files generated. The paths where the files are generated became incorrect. The path of the SGML path was wrong. This change has been tested in the CI, down to v17. Locally, I have run tests with configure (with and without VPATH), as well as meson, on the three branches. Combo oversight in `fa88928470` and `1e68e43d3f`.

PostgreSQL Database Management System

This directory contains the source code distribution of the PostgreSQL database management system.

PostgreSQL is an advanced object-relational database management system that supports an extended subset of the SQL standard, including transactions, foreign keys, subqueries, triggers, user-defined types and functions. This distribution also contains C language bindings.

General documentation about this version of PostgreSQL can be found at https://www.postgresql.org/docs/devel/. In particular, information about building PostgreSQL from the source code can be found at https://www.postgresql.org/docs/devel/installation.html.

The latest version of this software, and related software, may be obtained at https://www.postgresql.org/download/. For more information look at our web site located at https://www.postgresql.org/.
