BufmgrCommit no-op since 2008, remaining uses?

Hi,

Whilst reading up on the transaction commit code, I noticed the following lines:

  /* Tell bufmgr and smgr to prepare for commit */
  BufmgrCommit();

BufmgrCommit does exactly nothing; it is an empty function and has
been since commit 33960006 in late 2008 when it stopped calling
smgrcommit().

All two usages of the function (in our code base) seem to be in
xact.c. Are we maintaining it for potential future use, or can the
function be removed?

Kind regards,

Matthias van de Meent
