Collations with nondeterministic comparison This adds a flag "deterministic" to collations. If that is false, such a collation disables various optimizations that assume that strings are equal only if they are byte-wise equal. That then allows use cases such as case-insensitive or accent-insensitive comparisons or handling of strings with different Unicode normal forms. This functionality is only supported with the ICU provider. At least glibc doesn't appear to have any locales that work in a nondeterministic way, so it's not worth supporting this for the libc provider. The term "deterministic comparison" in this context is from Unicode Technical Standard #10 (https://unicode.org/reports/tr10/#Deterministic_Comparison). This patch makes changes in three areas: - CREATE COLLATION DDL changes and system catalog changes to support this new flag. - Many executor nodes and auxiliary code are extended to track collations. Previously, this code would just throw away collation information, because the eventually-called user-defined functions didn't use it since they only cared about equality, which didn't need collation information. - String data type functions that do equality comparisons and hashing are changed to take the (non-)deterministic flag into account. For comparison, this just means skipping various shortcuts and tie breakers that use byte-wise comparison. For hashing, we first need to convert the input string to a canonical "sort key" using the ICU analogue of strxfrm().

Remove distprep A PostgreSQL release tarball contains a number of prebuilt files, in particular files produced by bison, flex, perl, and well as html and man documentation. We have done this consistent with established practice at the time to not require these tools for building from a tarball. Some of these tools were hard to get, or get the right version of, from time to time, and shipping the prebuilt output was a convenience to users. Now this has at least two problems: One, we have to make the build system(s) work in two modes: Building from a git checkout and building from a tarball. This is pretty complicated, but it works so far for autoconf/make. It does not currently work for meson; you can currently only build with meson from a git checkout. Making meson builds work from a tarball seems very difficult or impossible. One particular problem is that since meson requires a separate build directory, we cannot make the build update files like gram.h in the source tree. So if you were to build from a tarball and update gram.y, you will have a gram.h in the source tree and one in the build tree, but the way things work is that the compiler will always use the one in the source tree. So you cannot, for example, make any gram.y changes when building from a tarball. This seems impossible to fix in a non-horrible way. Second, there is increased interest nowadays in precisely tracking the origin of software. We can reasonably track contributions into the git tree, and users can reasonably track the path from a tarball to packages and downloads and installs. But what happens between the git tree and the tarball is obscure and in some cases non-reproducible. The solution for both of these issues is to get rid of the step that adds prebuilt files to the tarball. The tarball now only contains what is in the git tree (*). Getting the additional build dependencies is no longer a problem nowadays, and the complications to keep these dual build modes working are significant. And of course we want to get the meson build system working universally. This commit removes the make distprep target altogether. The make dist target continues to do its job, it just doesn't call distprep anymore. (*) - The tarball also contains the INSTALL file that is built at make dist time, but not by distprep. This is unchanged for now. The make maintainer-clean target, whose job it is to remove the prebuilt files in addition to what make distclean does, is now just an alias to make distprep. (In practice, it is probably obsolete given that git clean is available.)
