This adds a check on the recursion depth when including authentication configuration files, something that has never been done when processing '@' files for database and user name lists in pg_hba.conf. On HEAD, this was leading to a rather confusing error, as of: FATAL: exceeded maxAllocatedDescs (NN) while trying to open file "/path/blah.conf" This refactors the code so as the error reported is now the following, which is the same as for GUCs: FATAL: could not open file "/path/blah.conf": maximum nesting depth exceeded This reduces a bit the verbosity of the error message used for files included in user and database lists, reporting only the file name of what's failing to load, without mentioning the relative or absolute path specified after '@' in a HBA file. The absolute path is built upon what '@' defines anyway, so there is no actual loss of information. This makes the future inclusion logic much simpler. A follow-up patch will add an error context to be able to track on which line of which file the inclusion is failing, to close the loop, providing all the information needed to know the full chain of events. This logic has been extracted from a larger patch written by Julien, rewritten by me to have a unique code path calling AllocateFile() on authentication files, and is useful on its own. This new interface will be used later for authentication files included with @include[_dir,_if_exists], in a follow-up patch.

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/.
