Robert Haas reported that his older clang compiler didn't like the two
Asserts which were verifying that the given MemoryContextMethodID was <=
MEMORY_CONTEXT_METHODID_MASK when building with
-Wtautological-constant-out-of-range-compare. In my (David's) opinion,
the compiler is wrong to warn about that. Newer versions of clang don't
warn about the out of range enum value, so perhaps this was a bug that has
now been fixed. To keep older clang versions happy, let's just cast the
enum value to int to stop the compiler complaining.
The main reason for the Asserts mentioned above to exist are to inform
future developers which are adding new MemoryContexts if they run out of
bit space in MemoryChunk to store the MemoryContextMethodID. As pointed
out by Tom Lane, it seems wise to also add a comment to the header for
that enum to document the restriction on these enum values.
Additionally, also fix an incorrect usage of UINT64CONST() which was
introduced in

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. 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/.
