Description

Comments in Cypher block using /* comment like this */ are ignored as expected
but --comments like these
cause ERROR. See examples below

This works as expected

select * from cypher('agc_graph',$$
return 'hello' /* ignore this comment */
$$) as (hi agtype);

hi
---------
"hello"
(1 row)

This does not work as expected

postgres=#
select * from cypher('agc_graph',$$
return 'hello' – ignore this comment
$$) as (hi agtype);

ERROR: syntax error at or near "this"
LINE 2: return 'hello' – ignore this comment
