This reworks the reloption parsing and build of a couple of index AMs by creating new structures for each index AM's options. This split was already done for BRIN, GIN and GiST (which actually has a fillfactor parameter), but not for hash, B-tree and SPGiST which relied on StdRdOptions due to an overlap with the default option set. This saves a couple of bytes for rd_options in each relcache entry with indexes making use of relation options, and brings more consistency between all index AMs. While on it, add a couple of AssertMacro() calls to make sure that utility macros to grab values of reloptions are used with the expected index AM.

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/.
