Things look like POSIX expressions to me. Also looks like the manuals
for regexp were not included because postgres simply links to the regex
library documented elswhere. Try these two sources:

http://tiger8.com/us/regexp-manpage.html (complete but too formal)
http://www.blighty.com/products/spade/help/d_regex.htm (informal but incomplete)

try (((^charl|^jam)es)|(^bob))

Does someone have the Python interface handling large objects
properly? I keep winding up with size 0 objects in PostgreSQL 6.3.2.
