Mark Dilger pointed out that the bootstrap parser does not allow any of its keywords to appear as column values unless they're quoted, and proposed dealing with that by quoting such values in genbki.pl. Looking closer, though, we also have that problem with respect to table, column, and type names appearing in the .bki file: the parser would fail if any of those matched any of its keywords. While so far there have been no conflicts (that I've heard of), this seems like a booby trap waiting to catch somebody. Rather than clutter genbki.pl with enough quoting logic to handle all that, let's make the bootstrap parser grow up a little bit and treat its keywords as unreserved. Experimentation shows that it's fairly easy to do so with the exception of _null_, which I don't have a big problem with keeping as a reserved word. The only change needed is that we can't have the "close" command take an optional table name: it has to either require or forbid the table name to avoid shift/reduce conflicts. genbki.pl has historically always included the table name, so I took that option. The implementation has bootscanner.l passing forward the string value of each keyword, in case bootparse.y needs that. This avoids needing to know the precise spelling of each keyword in bootparse.y, which is good because that's not always obvious from the token name.

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.
