Comment(by erilem):

 So this ticket's description reports about

 {{{
 SELECT ST_AsBinary('POINT(1 2)');
 }}}

 failing with this error:

 {{{
 ERROR:  function ST_AsBinary(unknown) is not unique
 }}}

 I've myself reported on a UNION-based query that also fails with a
 similar, though different error:

 {{{
 ERROR:  function ST_AsBinary(bytea) is not unique
 }}}

 Here's a simpler query that triggers the same error:

 {{{
 SELECT As_AsBinary(ST_AsBinary(ST_GeomFromText('POINT(1 2)')));
 }}}

 {{{ST_AsBinary}}} returns a {{{bytea}}}, which is a type that
 {{{ST_AsBinary}}} does no longer accept as its input argument.
