Because PostgreSQL::Version is very nuanced about development version numbers, the comparison to 16beta2 makes it think that that release is older than 16, therefore applying a database tweak that doesn't work there (the comparison is only supposed to match when run on version 15). As suggested by Andrew Dunstan, fix by having AdjustUpgrade.pm public methods create a separate PostgreSQL::Version object to use for these comparisons, that only carries the major version number. While at it, have the same methods ensure that the objects given are of the expected type. Backpatch to 16. This module goes all the way back to 9.2, but there's probably no need for this fix except where betas still live.

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.
