I'm quite fond of doing VPATH builds, i.e. building outside the source
tree. This also catches lots of little Makefile bugs, so here's a small
patch for one of them (replacing an explicit reference to thread.c with
a reference to it as the first prerequsite of the rule makes make look
for it in the place where it was found (the source tree) rather than in
the build tree. (using GNU make 3.79.1)

Include 'IPv4', 'IPv6', or 'Unix' in socket-creation failure messages,

Rewriter and planner should use only resno, not resname, to identify
target columns in INSERT and UPDATE targetlists. Don't rely on resname
to be accurate in ruleutils, either. This fixes bug reported by
Donald Fraser, in which renaming a column referenced in a rule did not
work very well.

Applied patch from Kim Ho to fix a regression against a 7.4 server. The result
of transaction isolation level changed from uppercase to lower case between 7.3 and 7.4. In testing, a regression was also fixed in this area when talking to
a 7.2 server due to changes in how notice messages are processed in the current
code.

Code cleanup inspired by recent resname bug report (doesn't fix the bug
yet, though). Avoid using nth() to fetch tlist entries; provide a
common routine get_tle_by_resno() to search a tlist for a particular
resno. This replaces a couple uses of nth() and a dozen hand-coded
search loops. Also, replace a few uses of nth(length-1, list) with
llast().

Repair potential deadlock created by recent changes to recycle btree
index pages: when _bt_getbuf asks the FSM for a free index page, it is
possible (and, in some cases, even moderately likely) that the answer
will be the same page that _bt_split is trying to split. _bt_getbuf
already knew that the returned page might not be free, but it wasn't
prepared for the possibility that even trying to lock the page could
be problematic. Fix by doing a conditional rather than unconditional
grab of the page lock.

Sometimes the third time is the charm. Third try to fix the sql injection
vulnerability. This fix completely removes the ability (hack) of being able
to bind a list of values in an in clause. It was demonstrated that by allowing
that functionality you open up the possibility for certain types of
sql injection attacks. The previous fix attempts all focused on preventing
the insertion of additional sql statements (the semi-colon problem:
xxx; any new sql statement here). But that still left the ability to
change the where clause on the current statement or perform a subselect
which can circumvent applicaiton security logic and/or allow you to call
any stored function.
