As added in 1de09ad8eb1fa673ee7899d6dfbb2b49ba204818 the new functions all accept signed integers as parameters. That's not great, because it's perfectly reasonable to call them with unsigned parameters. Unfortunately unsigned to signed conversion is not well defined, when exceeding the range of the signed value. That's presently not a practical issue in postgres (among other reasons because we force gcc's hand with -fwrapv). But it's clearly not quite right. Thus change the signatures to accept unsigned integers instead, signed to unsigned conversion is always well defined. Also change the backward compat pq_sendint() - while it's deprecated it seems better to be consistent. Per discussion between Andrew Gierth, Michael Paquier, Alvaro Herrera and Tom Lane.

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/.
