So I cannot rely on the like operator to behave correct if I'd like to
compare strings with backslashes (e.g. filepaths from MS Windows
filesystems)?
I actually get the same if it doesnt end with the slashes:
testdb=# select E'\\t' like E'\\t'; ?column?
---------- f
(1 row)
testdb=# select E'\\t' = E'\\t'; ?column?
---------- t
(1 row)
