Really?  LIKE is just a different spelling for operator ~~, and there is
nothing stopping people from defining more operators named that, not to
mention that there are already four of them in core PG.  In particular
the bytea ~~ bytea version is explicitly intended to provide a LIKE
implementation for non-text types.  I see some operators named ~~ in
contrib as well.
