Add the ability to label a column's default value in the catalog header, and implement this for pg_attribute. A new function in Catalog.pm is used to fill in a tuple with defaults. The build process will complain loudly if a catalog entry is incomplete, Commit 8137f2c3232 labeled variable length columns for the C preprocessor. Expose that label to genbki.pl so we can exclude those columns from schema macros in a general fashion. Also, format schema macro entries according to their types. This means slightly less code maintenance, but more importantly it's a proving ground for mechanisms intended to be used in later commits. While at it, I (Álvaro) couldn't resist making some changes in genbki.pl: rename some functions to actually indicate their purpose instead of actively misleading onlookers; and don't iterate on the whole of pg_type to find the entry for each catalog row, using a hash instead of an array.

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.
