The list of TokenizedAuthLines generated at parsing for the HBA and ident files is now stored in a static context called tokenize_context, where only all the parsed tokens are stored. This context is created when opening the first authentication file of a HBA/ident set (hba_file or ident_file), and is cleaned up once we are done all the work around it through a new routine called free_auth_file(). One call of open_auth_file() should have one matching call of free_auth_file(), the creation and deletion of the tokenization context is controlled by the recursion depth of the tokenization. Rather than having tokenize_auth_file() return a memory context that includes all the records, the tokenization logic now creates and deletes one memory context each time this function is called. This will simplify recursive calls to this routine for the upcoming inclusion record logic. While on it, rename tokenize_inc_file() to tokenize_expand_file() as this would conflict with the upcoming patch that will add inclusion records for HBA/ident files. An '@' file has its tokens added to an existing list. Reloading HBA/indent configuration in a tight loop shows no leaks, as of one type of test done (with and without -DEXEC_BACKEND).

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/.
