This isn't a PostgreSQL issue, but rather one of understanding how
regular expressions work in general. See the previously mentioned
"Pattern Matching" section of the PostgreSQL documentation for the
PostgreSQL-specific details, and use a search engine to find a
regular expression tutorial; they're frequently used in Perl and
other languages so a lot of learning material exists. If you can
find a copy in a library or bookstore, the book _Mastering Regular
Expressions_ by Jeffrey E. F. Friedl, published by O'Reilly, is a
good resource.
