The commentary in this file was in extremely sad shape. The author(s) had clearly never heard of the project convention that a function header comment should provide an API spec of some sort for that function. Much of it was flat out wrong, too --- maybe it was accurate when written, but if so it had not been updated to track subsequent code revisions. Rewrite and rearrange to try to bring it up to speed, and annotate some of the places where more work is needed. (I've refrained from actually fixing anything of substance ... yet.) Also, rename a couple of functions for more clarity as to what they do, do some very minor code rearrangement, remove some pointless Asserts, fix an incorrect Assert in readMessageFromPipe, and add a missing socket close in one error exit from pgpipe(). The last would be a bug if we tried to continue after pgpipe() failure, but since we don't, it's just cosmetic at present. Although this is only cosmetic, back-patch to 9.3 where parallel.c was added. It's sufficiently invasive that it'll pose a hazard for future back-patching if we don't.

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.
