Several backend-side loops scanning one or more directories with ReadDir() (WAL segment recycle/removal in xlog.c, backend-side directory copy, temporary file removal, configuration file parsing, some logical decoding logic and some pgtz stuff) already know the type of the entry being scanned thanks to the dirent structure associated to the entry, on platforms where we know about DT_REG, DT_DIR and DT_LNK to make the difference between a regular file, a directory and a symbolic link. Relying on the direct structure of an entry saves a few system calls to stat() and lstat() in the loops updated here, shaving some code while on it. The logic of the code remains the same, calling stat() or lstat() depending on if it is necessary to look through symlinks.

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/.
