format it as a date. With 7.0.x, I just

 select ts from foo order by ts desc limit 1

and in java: d = res.getDate(1);

but this fails everywhere in my code now :(

  The ResultSet.getXXX methods will attempt to
  convert whatever SQL type was returned by the
  database to whatever Java type is returned by
  the getXXX method.

when added by alter table add constraint.  The first file
patches backend/commands/command.c and the latter is a patch
to the alter table regression test.

basically want your guys feedback.  I have sprinkled some of my q's thru
the text delimited with the @@ symbol.  It seems to work perfectly.

[ Removed @@ comments because patch was reviewed. ]

At the moment it does CHECK constraints only, with inheritance.  However,
due to the problem mentioned before with the mismatching between inherited
constraints it may be wise to disable the inheritance feature for a while.
it is written in an extensible fashion to support future dropping of other
types of constraint, and is well documented.

Please send me your comments, check my use of locking, updating of
indices, use of ERROR and NOTICE, etc. and I will rework the patch based
on feedback until everyone
is happy with it...

    However, my application requires that each collection will also have a
    unique name. Why? So that a human being who wants to modify a collection
    will be able to identify it. It's much harder to know, if you have two
    collections named "Life Science", the the one tagged 24433 is the one
you
    need, and the one tagged 29882 is not

    I think 'the the' shouldn't be repeated twice. Although taken from an
email it would be cool to fix.

PG_RETURN_BOOL(0) instead of return 0.

from an empty text string.  This makes them consistent with the de facto
behavior of type char's I/O conversion functions, and avoids generating
text values with embedded nulls, which confuse many text operators.

which says that PERFORM will execute any SELECT query and discard the
result.  The former implementation would in fact raise an error if the
result contained more than one row or more than one column.

Also, change plpgsql's error-logging mechanism to emit the additional
messages about error location at NOTICE rather than DEBUG level.  This
allows them to be seen by the client without having to dig into the
postmaster log file (which may be nonexistent or inaccessible by the
client).

data.

Indicies: palm_buy_date_idx
          palm_user_date_idx
Primary Key: palm_buyers_pkey
Unique Key: palm_buyers_username
Constraint: "$1" ((sex = 'M'::bpchar) OR (sex = 'F'::bpchar))

Note that check constraint name now shown as well.  (Makes it a lot easier
to test inheritance support in ADD/DROP constraint :) )

Attached is a docs change for psql.

non-unique: stay as they were
unique and primary: become listed as primary keys
unique and non-primary: become listed as unique keys

I also made it so that it shows the names of check constraints ie:

Check: "$1" (a > 5)

from GMT (ie. -06:30).

the same tuple slot that the raw tuple came from, because that slot has
the wrong tuple descriptor.  Store it into its own slot with the correct
descriptor, instead.  This repairs problems with SPI functions seeing
inappropriate tuple descriptors --- for example, plpgsql code failing to
cope with SELECT FOR UPDATE.

Rather surprising we hadn't seen bug reports about this ...

in c.h we should be using the visible structure.  We should only see
de-TOASTed values in this program.  The old method refused to compile
because the length macro was no longer an lvalue.

privileges.  INSERT and COPY FROM now require INSERT (only).  Add
privileges regression test.

could be changed if we create a new Python type that matches it better
but NUMERIC <==> FLOAT probably works fine for most cases.

Python) to support shared extension modules, I have learned that Guido
prefers the style of the attached patch to solve the above problem.
I feel that this solution is particularly appropriate in this case
because the following:

    PglargeType
    PgType
    PgQueryType

are already being handled in the way that I am proposing for PgSourceType.
