Between 1st (The LIKE expression...) and 2nd (If pattern does not...)
paragraphs, it could be added something like:
<begin>
Caution
Contrary to some other databases, in Postgresql only two characters
are used in LIKE patterns: underscore (_) and percent sign (%).
The use of any other character will lead to an error.
<end>
The error message also would be more clarified to inform user about
the use of not supported characters.
