Solaris 11.4 has built-in functions named b64_encode and b64_decode. Rename ours to something else to avoid the conflict (fortunately, ours are static so the impact is limited). One could wish for less duplication of code in this area, but that would be a larger patch and not very suitable for back-patching. Since this is a portability fix, we want to put it into all supported branches. Report and initial patch by Rainer Orth, reviewed and adjusted a bit by Michael Paquier Discussion: https://postgr.es/m/ydd372wk28h.fsf@CeBiTec.Uni-Bielefeld.DE
The PostgreSQL contrib tree --------------------------- This subtree contains porting tools, analysis utilities, and plug-in features that are not part of the core PostgreSQL system, mainly because they address a limited audience or are too experimental to be part of the main source tree. This does not preclude their usefulness. User documentation for each module appears in the main SGML documentation. When building from the source distribution, these modules are not built automatically, unless you build the "world" target. You can also build and install them all by running "make all" and "make install" in this directory; or to build and install just one selected module, do the same in that module's subdirectory. Some directories supply new user-defined functions, operators, or types. To make use of one of these modules, after you have installed the code you need to register the new SQL objects in the database system by executing a CREATE EXTENSION command. In a fresh database, you can simply do CREATE EXTENSION module_name; See the PostgreSQL documentation for more information about this procedure.
