effectively used to mean a default value that could also be spelled out explicitly. (ACLs behave that way, and useconfig/datconfig do too IIRC.) It's a bit of a hack, but it saves table space and backend code --- without this convention the default would have to be inserted "manually" since we have no mechanism to supply defaults when C code is forming a new catalog tuple. I'm inclined to leave the code alone. But Alvaro is right that it'd be good to point out the 'infinity' option in the CREATE USER and ALTER USER man pages. (Doc patch please?) Alvaro Herrera
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 several language bindings, including C, Perl, Python, and Tcl, as well as a JDBC driver. The ODBC and C++ interfaces have been moved to the PostgreSQL Projects Web Site at http://gborg.postgresql.org for separate maintenance. 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 ftp://ftp.postgresql.org/pub/. For more information look at our web site located at http://www.postgresql.org/.
