- Note that the backslash already has a special meaning in string literals,
- so to write a pattern constant that contains a backslash you must write two
- backslashes in an SQL statement (assuming escape string syntax is used, see
- <xref linkend="sql-syntax-strings">). Thus, writing a pattern that
- actually matches a literal backslash means writing four backslashes in the
- statement. You can avoid this by selecting a different escape character
- with <literal>ESCAPE</literal>; then a backslash is not special to
- <function>LIKE</function> anymore. (But backslash is still special to the
- string literal parser, so you still need two of them to match a backslash.)
