5c63975504 Float-to-int conversion functions should return NULL when given NULL
input, not throw a gratuitous elog().

37ab088770 Remove no-longer-necessary restriction against uplevel correlation vars
outside WHERE clause.  Fix a couple of places that didn't handle uplevel
refs cleanly.

dadb14fa60 Hack parse_coerce so it won't try to constant-fold the dummy Const
nodes introduced by make_subplan().  It'd be better if we used a
different node type for subplan result placeholders, but for now...

Const placeholder nodes for subplan result values.

1afaa2557a If we cannot get a real estimate for the selectivity of a range query,
use a default value that's fairly small.  We were generating a result
of about 0.1, but I think 0.01 is probably better --- want to encourage
use of an indexscan in this situation.

cad764f349 Improve selectivity estimation involving string constants: pay attention
to more than one character, and try to do the right thing in non-ASCII
locales.

1d5e7a6f46 Repair logic flaw in cost estimator: cost_nestloop() was estimating CPU
costs using the inner path's parent->rows count as the number of tuples
processed per inner scan iteration.  This is wrong when we are using an
inner indexscan with indexquals based on join clauses, because the rows
count in a Relation node reflects the selectivity of the restriction
clauses for that rel only.  Upshot was that if join clause was very
selective, we'd drastically overestimate the true cost of the join.
Fix is to calculate correct output-rows estimate for an inner indexscan
when the IndexPath node is created and save it in the path node.
Change of path node doesn't require initdb, since path nodes don't
appear in saved rules.

3ee8f7e207 Restructure planning code so that preprocessing of targetlist and quals
to simplify constant expressions and expand SubLink nodes into SubPlans
is done in a separate routine subquery_planner() that calls union_planner().
We formerly did most of this work in query_planner(), but that's the
wrong place because it may never see the real targetlist.  Splitting
union_planner into two routines also allows us to avoid redundant work
when union_planner is invoked recursively for UNION and inheritance
cases.  Upshot is that it is now possible to do something like
select float8(count(*)) / (select count(*) from int4_tbl)  from int4_tbl
group by f1;
which has never worked before.

fdd7f59820 Since PORTNAME is no longer used at the level of C code (it's only in
Makefiles now), there's no reason for os2client to maintain its own
copy of c.h just to change #define PORTNAME.  Simplify Makefile
accordingly.  Get rid of horribly-out-of-date modified copy of c.h,
which should never have been in the distribution to start with,
since it's actually a derived file.  Now it's not needed anyway.

a73b75615f transformExpr() did the Wrong Thing if applied to a SubLink node that
had already been transformed.  This led to failure in examples like
UPDATE table SET fld = (SELECT ...).  Repair this, and revise the
comments to explain that transformExpr has to be robust against this
condition.  Someday we might want to fix the callers so that
transformExpr is never invoked on its own output, but that someday
is not today.

52d0265736 it seems in the beta2 release DBUSERID in pg_dumpall is the _name_ of the
user, so it doesn't need to be translated from the number to the name.

also ``create database ...'' does not take numbers for the encoding, so
the ENCODING variable does not need to be translated to a number, but left
as the text representation.  a patch is supplied to make the changes i
have found to work.  i was successful dumping and reloading my database
after these changes.

cfa929f601 Fix incorrect implementation of log(x) for numeric, as well as

440b0fea3d Another go-round with resolution of ambiguous functions and operators.
In function parsing, try for an actual function of the given name and
input types before trying to interpret the function call as a type
coercion request, rather than after.  Before, a function that had the
same name as a type and operated on a binary-compatible type wouldn't
get invoked.  Also, cross-pollinate between func_select_candidates and
oper_select_candidates to ensure that they use as nearly the same
resolution rules as possible.  A few other minor code cleanups too.

d63e05a638 Improve error message wording in unary_op_error() --- suggest that
problem could be lack of parentheses.  This addresses cases like
X UserOp UserOp Y, which will be parsed as (X UserOp) UserOp Y,
whereas what likely was wanted was X UserOp (UserOp Y).

f945f46193 Modify lexing of multi-char operators per pghackers discussion around
16-Mar-00: trailing + or - is not part of the operator unless the operator
also contains characters not present in SQL92-defined operators.  This
solves the 'X=-Y' problem without unduly constraining users' choice of
operator names --- in particular, no existing Postgres operator names
become invalid.

Also, remove processing of // comments, as agreed in the same thread.
