All but a few existing callers assume without checking that this function succeeds. While it probably will, that's a poor excuse for not checking. Let's make it return void and instead throw an error if it doesn't find the block reference. Callers that actually need to handle the no-such-block case must now use the underlying function XLogRecGetBlockTagExtended. In addition to being a bit less error-prone, this should also serve to suppress some Coverity complaints about XLogRecGetBlockRefInfo. While at it, clean up some inconsistency about use of the XLogRecHasBlockRef macro: make XLogRecGetBlockTagExtended use that instead of open-coding the same condition, and avoid calling XLogRecHasBlockRef twice in relevant code paths. (That is, calling XLogRecHasBlockRef followed by XLogRecGetBlockTag is now deprecated: use XLogRecGetBlockTagExtended instead.) Patch HEAD only; this doesn't seem to have enough value to consider a back-branch API break. Discussion: https://postgr.es/m/425039.1649701221@sss.pgh.pa.us |

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/.
