These appear to be related.  The following query produces the former,
but if you replace the very last reference of provider with the literal
'bar', it raises the latter error.

select 1 from
  pg_catalog.pg_shseclabel as rel_09
      inner join public.rtest_view2 as rel_32
          left join pg_catalog.pg_roles as rel_33
          on (rel_32.a = rel_33.rolconnlimit )
      on (rel_09.provider = rel_33.rolpassword )
    left join pg_catalog.pg_user as rel_35
    on (rel_33.rolconfig = rel_35.useconfig )
where ( ((rel_09.provider ~<~ 'foo')
      and (rel_35.usename ~* rel_09.provider)));
