This makes it possible to use the functions without getting errors, if there is a chance that the file might be removed or renamed concurrently. pg_rewind needs to do just that, although this could be useful for other purposes too. (The changes to pg_rewind to use these functions will come in a separate commit.) The read_binary_file() function isn't very well-suited for extensions.c's purposes anymore, if it ever was. So bite the bullet and make a copy of it in extension.c, tailored for that use case. This seems better than the accidental code reuse, even if it's a some more lines of code. Michael Paquier, with plenty of kibitzing by me. |

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: http://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.
