those process types that go through InitPostgres; in particular, bootstrap and standalone-backend cases. This ensures that we have set up a PGPROC and done some other basic initialization steps (corresponding to the if (IsUnderPostmaster) block in AuxiliaryProcessMain) before we attempt to run WAL recovery in a standalone backend. As was discovered last September, this is necessary for some corner-case code paths during WAL recovery, particularly end-of-WAL cleanup. Moving the bootstrap case here too is not necessary for correctness, but it seems like a good idea since it reduces the number of distinct code paths.
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: http://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. Changes between all PostgreSQL releases are recorded in the file HISTORY. 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 http://www.postgresql.org/download/. For more information look at our web site located at http://www.postgresql.org/.
