Leer el manual
http://www.postgresql.org/docs/8.1/static/functions-matching.html#FUNCTIONS-LIKE
To match a literal underscore or percent sign without matching
other characters, the respective character in pattern must be
preceded by the escape character. The default escape character
is the backslash but a different one may be selected by using
the ESCAPE clause. To match the escape character itself, write
two escape characters.
