Is there a way to search for rows with the character \?
I tried variants of like and ~.
create table mytable (f1 text);
insert into mytable values ('Test row 1');
insert into mytable values (E'Test row 2 \\');
select * from mytable where f1 like E'%\\%'; <-- returned nothing
select * from mytable where f1 ~ '\'; <-- waiting for single quote
select * from mytable where f1 ~ E'\\'; <-- Error
And a few more variants.. with no valid reults.
Any suggestions?

Thus, writing a pattern that actually matches a literal backslash means writing four backslashes in the statement.
