compareentry() is declared to work on WordEntryIN structs, but tsvectorrecv() is using it in two places to work on WordEntry structs. This is almost okay, since WordEntry is the first field of WordEntryIN. But on machines with 8-byte pointers, WordEntryIN will have a larger alignment spec than WordEntry, and it's at least theoretically possible that the compiler could generate code that depends on the larger alignment. Given the lack of field reports, this may be just a hypothetical bug that upsets nothing except sanitizer tools. Or it may be real on certain hardware but nobody's tried to use tsvectorrecv() on such hardware. In any case we should fix it, and the fix is trivial: just change compareentry() so that it works on WordEntry without any mention of WordEntryIN. We can also get rid of the quite-useless intermediate function WordEntryCMP.

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/.
