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.

command, the entries in template/.similar can really be regular
expressions. This isn't a new feature, just an observation of what the
code already did.

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.

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.

incorrect descriptions of a couple of log-related functions.
I will not force an initdb for this, but log() on a numeric won't
work until you do one...

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.

actually returns the type it is named for.

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).

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.

unary plus, but at least with this fix the grammar will take it.

/tmp/trace.out.
However, elog.h uses DEBUG as a log-level flag. As a result, tracing is
turned on even if the libpq++.so is built with DEBUG commented out in
the Makefile.
This patch changes libpq++ to use DEBUGFILE instead (which is not
defined anywhere else).

We probably support a superset of the spec, but I don't have the spec
to confirm this.
Update regression tests to include tests for this format.

actually a type-coercion problem. If you have a function defined on
class A, and class B inherits from A, then the function ought to work
on class B as well --- but coerce_type didn't know that. Now it does.

mark query as having subselects if a subselect was added from a rule
WHERE condition (as opposed to a rule action). Also, fix adjustment
of varlevelsup so that it actually has some prospect of working when
inserting an expression containing a subselect into a subquery.
|
|
small changes in formatting.c code (better memory usage ...etc.) and
better
to_char's cache (will fastly for more to_char()s in one query).
(It is probably end of to_char() development in 7.0 cycle.)
