      Palak,

      <br>
      I did a quick review of the patch:
      <br>
      <br>
      +CREATE FUNCTION pg_buffercache_invalidate(IN int, IN bool default
      true)
      <br>
      +RETURNS bool
      <br>
      +AS 'MODULE_PATHNAME', 'pg_buffercache_invalidate'
      <br>
      +LANGUAGE C PARALLEL SAFE;
      <br>
      <br>
      --&gt; Not enforced anywhere, but you can also add a comment to
      the function, for end users...

    <p>The arguments should also have names...</p>

      +    force = PG_GETARG_BOOL(1);
      <br>
      <br>
      I think you also need to test PG_ARGISNULL with force parameter.

    Actually, that's true for the first argument as well. Or, just mark
    the function as STRICT.<br>
