Escaping special characters in to_tsquery

Question

How do you espace special characters in string passed to to_tsquery? For instance, this kind of query:

select to_tsquery(\'AT&T\');

Answer 1

A simple solution is to create the tsquery as follows:

select $$'AT&T'$$::tsquery;

You can make more complex queries:

select $$'AT&T' & Phone | '|Bang!'$$::tsquery;
