The freshly-released 2025a version of tzdata has a refined estimate for the longitude of Manila, changing their value for LMT in pre-standardized-timezone days. This changes the output of one of our test cases. Since we need to be able to run with system tzdata files that may or may not contain this update, we'd better stop making that specific test. I switched it to use Asia/Singapore, which has a roughly similar UTC offset. That LMT value hasn't changed in tzdb since 2003, so we can hope that it's well established. I also noticed that this set of make_timestamptz tests only exercises zones east of Greenwich, which seems rather sad, and was not the original intent AFAICS. (We've already changed these tests once to stabilize their results across tzdata updates, cf 66b737cd9; it looks like I failed to consider the UTC-offset-sign aspect then.) To improve that, add a test with Pacific/Honolulu. That LMT offset is also quite old in tzdb, so we'll cross our fingers that it doesn't get improved.

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. PostgreSQL has many language interfaces, many of which are listed here: https://www.postgresql.org/download/ See the file INSTALL for instructions on how to build and install PostgreSQL. That file also lists supported operating systems and hardware platforms and contains information regarding any other software packages that are required to build or run the PostgreSQL system. Copyright and license information can be found in the file COPYRIGHT. A comprehensive documentation set is included in this distribution; it can be read as described in the installation instructions. The latest version of this software may be obtained at https://www.postgresql.org/download/. For more information look at our web site located at https://www.postgresql.org/.
