Tom Lane [Sun, 7 May 2006 01:21:30 +0000 (01:21 +0000)]
Rewrite btree index scans to work a page at a time in all cases (both
btgettuple and btgetmulti).  This eliminates the problem of "re-finding" the
exact stopping point, since the stopping point is effectively always a page
boundary, and index items are never moved across pre-existing page boundaries.
A small penalty is that the keys_are_unique optimization is effectively
disabled (and, therefore, is removed in this patch), causing us to apply
_bt_checkkeys() to at least one more tuple than necessary when looking up a
unique key.  However, the advantages for non-unique cases seem great enough to
accept this tradeoff.  Aside from simplifying and (sometimes) speeding up the
indexscan code, this will allow us to reimplement btbulkdelete as a largely
sequential scan instead of index-order traversal, thereby significantly
reducing the cost of VACUUM.  Those changes will come in a separate patch.

Remove unused function SSL_CTX_set_tmp_dh_callback() from libpq:

In the SSL code in libpq it does some processing with DH parameters:

SSL_CTX_set_tmp_dh_callback()

This function is marked as server use only[1], the client always uses
the DH parameters in the server, so all the code in the client dealing
with the DH parameters is useless. This patch removes it.

It's not clear why the code was added in the first place, it's been
there almost since the beginning[2]. At the time there was a suggestion
of merging the front-end and backend SSL code, but looking at the
changes since, that seems unlikely.

As a further example, the s_server program allows you to specify DH
params, but s_client doesn't. In the GnuTLS documentation under
gnutls_dh_params_generate2() it says[3]:

  Also note that the DH parameters are only useful to servers. Since
  clients use the parameters sent by the server, it's of no use to call
  this in client side.
