- Remove MemoryContextAllocZeroAligned(). It was supposed to be a faster version of MemoryContextAllocZero(), but modern compilers turn the MemSetLoop() into a call to memset() anyway, making it more or less identical to MemoryContextAllocZero(). That was the only user of MemSetTest, MemSetLoop, so remove those too, as well as palloc0fast(). - Convert newNode() to a static inline function. When this was originally originally written, it was written as a macro because testing showed that gcc didn't inline the size check as we intended. Modern compiler versions do, and now that it just calls palloc0() there is no size-check to inline anyway. One nice effect is that the palloc0() takes one less argument than MemoryContextAllocZeroAligned(), which saves a few instructions in the callers of newNode().

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. 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.
