Description:

Table 9.14 Regular Expression Match Operators
It is not clear (to me)where I would put one of these operators. The Example
column does not make sense to me.

Uh, you can use those regular expressions any place you would use an
operator:

SELECT 'thomas' ~ '.*thomas.*';
?column?
----------
t

or in a where clause, e.g. WHERE col ~ 'ab.*c'. Not sure how we can
improve the docs here.
