Actually that's wrong, what he'd need is LIKE E'%abc\\_%'
(or omit the E and ignore the warning).
Alternatively, set standard_conforming_strings to TRUE and write
LIKE '%abc\_%' ... but beware that that might break other parts
of your app that are expecting backslash to be special.

Yeah, this might be the easiest localized solution.
