Give a more reasonable error message when lock file exists but has zero length; prior code confused this with could-not-read-file case.

predicate tester. It can now deal with commuted clauses (for instance, 4 < x implies x > 3), subclauses more complicated than a simple Var (for example, upper(x) = 't' implies upper(x) > 'a'), and <> operators (for example, x < 3 implies x <> 4). Still only understands operators associated with btree opclasses, though. Inspired by example from Martin Hampl.

pointer type when it is not necessary to do so. For future reference, casting NULL to a pointer type is only necessary when (a) invoking a function AND either (b) the function has no prototype OR (c) the function is a varargs function.

Dennis Bjorklund's original patch for function parameter names, but there's still plenty left to do (documentation for instance...)

parameters to be declared with names. pg_proc has a column to store names, and CREATE FUNCTION can insert data into it, but that's all as yet. I need to do more work on the pg_dump and plpgsql portions of the patch before committing those, but I thought I'd get the bulky changes in before the tree drifts under me. initdb forced due to pg_proc change.

- Update comment in IsReservedName() to the present day - Improve some variable & function names in commands/vacuum.c. I was planning to rewrite this to avoid lappend(), but since I still intend to do the list rewrite, there's no need for that. - Update some smgr comments which seemed to imply that we still forced all dirty pages to disk at commit-time. - Replace some #ifdef DIAGNOSTIC code with assertions. - Make the distinction between OS-level file descriptors and virtual file descriptors a little clearer in a few comments - Other minor comment improvements in the smgr code

regular qpqual ('filter condition'), add special-purpose code to nodeIndexscan.c to recheck them. This ends being almost no net addition of code, because the removal of planner code balances out the extra executor code, but it is significantly more efficient when a lossy operator is involved in an OR indexscan. The old implementation had to recheck the entire indexqual in such cases.

with index qual clauses in the Path representation. This saves a little work during createplan and (probably more importantly) allows reuse of cached selectivity estimates during indexscan planning. Also fix latent bug: wrong plan would have been generated for a 'special operator' used in a nestloop-inner-indexscan join qual, because the special operator would not have gotten into the list of quals to recheck. This bug is only latent because at present the special-operator code could never trigger on a join qual, but sooner or later someone will want to do it.

join conditions in which each OR subclause includes a constraint on the same relation. This implements the other useful side-effect of conversion to CNF format, without its unpleasant side-effects. As per pghackers discussion of a few weeks ago.

teaching the latter to accept either RestrictInfo nodes or bare clause expressions; and cache the selectivity result in the RestrictInfo node when possible. This extends the caching behavior of approx_selectivity to many more contexts, and should reduce duplicate selectivity calculations.
