This is a follow-up refactoring after 09ec55b and b674211, which has proved that the encoding and decoding routines used by SCRAM have a poor interface when it comes to check after buffer overflows. This adds an extra argument in the shape of the length of the result buffer for each routine, which is used for overflow checks when encoding or decoding an input string. The original idea comes from Tom Lane. As a result of that, the encoding routine can now fail, so all its callers are adjusted to generate proper error messages in case of problems. On failure, the result buffer gets zeroed. Author: Michael Paquier Reviewed-by: Daniel Gustafsson Discussion: https://postgr.es/m/20190623132535.GB1628@paquier.xyz

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/.
