sendFileWithContent() previously got the content length by using strlen(), assuming that the content given is always a string. Some patches are under discussion to pass binary contents to a base backup stream, where an arbitrary length needs to be given by the caller instead. The patch extends sendFileWithContent() to be able to handle this case, where len < 0 can be used to indicate an arbitrary length rather than rely on strlen() for the content length. A comment in sendFileWithContent() mentioned the backup_label file. However, this routine is used by more file types, like the tablespace map, so adjust it in passing.

This distribution also contains C language bindings. 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.
