Good eye. Yes, it was wrong. To fix it, edit
/pgsql/src/include/catalog/pg_operator.h.

Search for the strings 'lseq_eq'. The first instance is correct, but
the second instance should be 'lseg_neq'. Then you must run initdb to
reload the system tables.

Another way to do this would be to do an update on 'pg_operator'. I
believe the oid is 1586, and the field is oprcode, so you can try:

update pg_operator
set oprcode = 'lseg_neq'
where oid = 1586

\do should then show the proper values.
