Andres Freund	01d6832c10	meson: add and use stamp files for generated headers Without using stamp files, meson lists the generated headers as the dependency for every .c file, bloating build.ninja by more than 2x. Processing all the dependencies also increases the time to generate build.ninja. The immediate benefit is that this makes re-configuring and clean builds a bit faster. The main motivation however is that I have other patches that introduce additional build targets that further would increase the size of build.ninja, making re-configuring more noticeably slower.

Peter Eisentraut	6fdd5d9563	Drop warning-free support for Flex 2.5.35 This removes all the various workarounds for avoiding compiler warnings with Flex 2.5.35. Several recent patches have added additional warnings that would either need to be fixed along the lines of the existing workarounds, or we decide to no longer care about this, which we do here. Flex 2.5.35 is extremely outdated, and you can't even download it anymore from any of the Flex project sites, so it's nearly impossible to support. After this, using Flex 2.5.35 will still work, but the generated code will produce numerous compiler warnings.

Robert Haas	f80b09bac8	Move astreamer (except astreamer_inject) to fe_utils. This allows the code to be used by other frontend applications. Amul Sul, reviewed by Sravan Kumar, Andres Freund (whose input I specifically solicited regarding the meson.build changes), and me.

Andres Freund	e5555657ba	meson: Add support for building with precompiled headers This substantially speeds up building for windows, due to the vast amount of headers included via windows.h. A cross build from linux targetting mingw goes from 994.11user 136.43system 0:31.58elapsed 3579%CPU to 422.41user 89.05system 0:14.35elapsed 3562%CPU The wins on windows are similar-ish (but I don't have a system at hand just now for actual numbers). Targetting other operating systems the wins are far smaller (tested linux, macOS, FreeBSD). For now precompiled headers are disabled by default, it's not clear how well they work on all platforms. E.g. on FreeBSD gcc doesn't seem to have working support, but clang does. When doing a full build precompiled headers are only beneficial for targets with multiple .c files, as meson builds a separate precompiled header for each target (so that different compilation options take effect). This commit therefore only changes target with at least two .c files to use precompiled headers. Because this commit adds b_pch=false to the default_options new build directories will have precompiled headers disabled by default, however existing build directories will continue use the default value of b_pch, which is true. Note that using precompiled headers with ccache requires setting CCACHE_SLOPPINESS=pch_defines,time_macros to get hits.

Andres Freund	4289263cf2	windows: Adjust FD_SETSIZE via commandline define When using precompiled headers, we cannot pre-define macros for the system headers from within .c files, as headers are already processed before the #define in the C file is reached. But we can pre-define using -DFD_SETSIZE, as long as that's also used when building the precompiled header. A few files #define FD_SETSIZE 1024 on windows, as the default is only 64. I am hesitant to change FD_SETSIZE globally on windows, due to src/backend/port/win32/socket.c using it to size on-stack arrays. Instead add -DFD_SETSIZE=1024 when building the specific targets needing it. We likely should move away from using select() in those places, but that's a larger change.

Andres Freund	e6927270cd	meson: Add initial version of meson based build system Autoconf is showing its age, fewer and fewer contributors know how to wrangle it. Recursive make has a lot of hard to resolve dependency issues and slow incremental rebuilds. Our home-grown MSVC build system is hard to maintain for developers not using Windows and runs tests serially. While these and other issues could individually be addressed with incremental improvements, together they seem best addressed by moving to a more modern build system. After evaluating different build system choices, we chose to use meson, to a good degree based on the adoption by other open source projects. We decided that it's more realistic to commit a relatively early version of the new build system and mature it in tree. This commit adds an initial version of a meson based build system. It supports building postgres on at least AIX, FreeBSD, Linux, macOS, NetBSD, OpenBSD, Solaris and Windows (however only gcc is supported on aix, solaris). For Windows/MSVC postgres can now be built with ninja (faster, particularly for incremental builds) and msbuild (supporting the visual studio GUI, but building slower). Several aspects (e.g. Windows rc file generation, PGXS compatibility, LLVM bitcode generation, documentation adjustments) are done in subsequent commits requiring further review. Other aspects (e.g. not installing test-only extensions) are not yet addressed. When building on Windows with msbuild, builds are slower when using a visual studio version older than 2019, because those versions do not support MultiToolTask, required by meson for intra-target parallelism. The plan is to remove the MSVC specific build system in src/tools/msvc soon after reaching feature parity. However, we're not planning to remove the autoconf/make build system in the near future. Likely we're going to keep at least the parts required for PGXS to keep working around until all supported versions build with meson.
