This breaks the principle that common/ ought not depend on anything in the server, not only code-wise but in the headers. The only arguable advantage is avoidance of duplication of half a dozen extern declarations, and even that is rather dubious, considering that the previous coding was wrong about which declarations to duplicate: it exposed pnstrdup() to frontend code even though no such function is provided in fe_memutils.c. On the same principle, don't #include utils/memutils.h in the frontend build of psprintf.c. This requires duplicating the definition of MaxAllocSize, but that seems fine to me: there's no a-priori reason why frontend code should use the same size limit as the backend anyway. In passing, clean up some rather odd layout and ordering choices that were imposed on palloc.h to reduce the number of #ifdefs required by the previous approach. Per gripe from Christoph Berg. There's still more work to do to make include/common/ clean, but this part seems reasonably noncontroversial.
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. 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.
