This should be
INSERT INTO testing (test_text) values (E'abc\123');

Note that the String Constants section (4.1.2.1) says put the E
"before the opening single quote".

Also be sure to read the Caution section.
Using \ as an escape character is the old non-standard PostgreSQL
escape syntax that the WARNING (above) is, uh, warning you about.
With standard_conforming_strings on (i.e., follow the SQL spec), the
backslash is just a backslash character.

Depends on the setting of standard_conforming_strings.
