44b928e876 Add a new system view, pg_prepared_statements, that can be used to
access information about the prepared statements that are available
in the current session. Original patch from Joachim Wieland, various
improvements by Neil Conway.

The "statement" column of the view contains the literal query string
sent by the client, without any rewriting or pretty printing. This
means that prepared statements created via SQL will be prefixed with
"PREPARE ... AS ", whereas those prepared via the FE/BE protocol will
not. That is unfortunate, but discussion on -patches did not yield an
efficient way to improve this, and there is some merit in returning
exactly what the client sent to the backend.

Catalog version bumped, regression tests updated.

6e07709760 Implement SQL-compliant treatment of row comparisons for < <= > >= cases
(previously we only did = and <> correctly).  Also, allow row comparisons
with any operators that are in btree opclasses, not only those with these
specific names.  This gets rid of a whole lot of indefensible assumptions
about the behavior of particular operators based on their names ... though
it's still true that IN and NOT IN expand to "= ANY".  The patch adds a
RowCompareExpr expression node type, and makes some changes in the
representation of ANY/ALL/ROWCOMPARE SubLinks so that they can share code
with RowCompareExpr.

I have not yet done anything about making RowCompareExpr an indexable
operator, but will look at that soon.

* %Make row-wise comparisons work per SQL spec

  Right now, '(a, b) < (1, 2)' is processed as 'a < 1 and b < 2', but
  the SQL standard requires it to be processed as a column-by-column
  comparison, so the proper comparison is '(a < 1) OR (a = 1 AND b < 2)'.

2005-12-08 21:36:50 +00:00
Bruce Momjian
04db9d25d1 there's a paragraph in the ALTER TABLE reference page that reads:
DROP CONSTRAINT

    This form drops constraints on a table. Currently, constraints on tables
    are not required to have unique names, so there may be more than one
    constraint matching the specified name. All matching constraints will be
    dropped.

To my knowledge, it is no longer possible to create constraints with the
same name for the same relation. When you create a constraint and specify
the same name explictly, an error is raised. Implicit constraint creation
won't choose an existing name either and up to now you could not rename a
constraint. Renaming works with the patch I sent in a few hours ago but this
patch as well won't allow constraints with identical names on the same
relation.

The attached patch thus removes the note in the docs.

d20901a39b Allow to_char(interval) and to_char(time) to use AM/PM specifications.
Map them to a single day, so '30 hours' is 'AM'.

Have to_char(interval) and to_char(time) use "HH", "HH12" as 12-hour
intervals, rather than bypass and print the full interval hours.  This
is neeeded because to_char(time) is mapped to interval in this function.
Intervals should use "HH24", and document suggestion.

Allow "D" format specifiers for interval/time.
