and the editor's cursor will be initially placed on that line. In \e the
lines are counted with respect to the query buffer, while in \ef they are
counted with line 1 = first line of function body. These choices are useful
for positioning the cursor on the line of a previously-reported error.
To avoid assumptions about what switch the user's editor takes for this
purpose, invent a new psql variable EDITOR_LINENUMBER_SWITCH with (at
present) no default value.
One incompatibility from previous behavior is that "\e 1234" will now
take "1234" as a line number not a file name. There are at least two
ways to select a numerically-named file if you really want to.

There is much else to do here, but this patch seems useful in its own right
for as long as this code survives.

better handling of NULL elements within the arrays. The third parameter
is a string that should be used to represent a NULL element, or should
be translated into a NULL element, respectively. If the third parameter
is NULL it behaves the same as the two-parameter form.
There are two incompatible changes in the behavior of the two-parameter form
of string_to_array. First, it will return an empty (zero-element) array
rather than NULL when the input string is of zero length. Second, if the
field separator is NULL, the function splits the string into individual
characters, rather than returning NULL as before. These two changes make
this form fully compatible with the behavior of the new three-parameter form.

expressions. We need to deal with this when handling subscripts in an array
assignment, and also when catching an exception. In an Assert-enabled build
these omissions led to Assert failures, but I think in a normal build the
only consequence would be short-term memory leakage; which may explain why
this wasn't reported from the field long ago.
Back-patch to all supported versions. 7.4 doesn't have exceptions, but
otherwise these bugs go all the way back.

can be caught in the same places that could catch an ordinary RAISE ERROR
in the same location. The previous coding insisted on throwing the error
from the block containing the active exception handler; which is arguably
more surprising, and definitely unlike Oracle's behavior.
Not back-patching, since this is a pretty obscure corner case. The risk
of breaking somebody's code in a minor version update seems to outweigh
any possible benefit.

statistics counts. These numbers are being accumulated but haven't yet been
transmitted to the collector (and won't be, until the transaction ends).
For some purposes, though, it's handy to be able to look at them.

other columns to be referenced without listing them in GROUP BY, so long as
the primary key column(s) are listed in GROUP BY.
Eventually we should also allow functional dependency on a UNIQUE constraint
when the columns are marked NOT NULL, but that has to wait until NOT NULL
constraints are represented in pg_constraint, because we need to have
pg_constraint OIDs for all the conditions needed to ensure functional
dependency.

The old computation can sometimes underestimate the necessary space

isn't used for anything critical. Per discussion with Tom Lane,

implementation deficiencies. Per discussion of bug #5592, we're not
going to change it, but these things should be documented so that if
anyone ever reimplements type tinterval, they will be more careful.
Without this patch, constraints inherited by children of a parent
table which itself has multiple inheritance parents can end up with
the wrong coninhcount. After dropping the constraint, the children
end up with a leftover copy of the constraint that is not dumped
and cannot be dropped. There is a similar problem with ALTER TABLE
.. ADD COLUMN, but that looks significantly more difficult to
resolve, so I'm committing this fix separately.
Back-patch to 8.4, which is the first release that has coninhcount.

makeTSQuerySign. The first of these is a live bug, on some platforms,
as per bug #5590 from John Regehr. However the consequences seem limited
because of the relatively narrow scope of use of QTNode.sign. The shift in
makeTSQuerySign is actually safe because TSQS_SIGLEN is unsigned, but it
seems like a good idea to insert an explicit cast rather than depend on that.
tsqueries. CompareTSQ has to have a guard for the case rather than blindly
applying QTNodeCompare to random data past the end of the datums. Also,
change QTNodeCompare to be a little less trusting: use an actual test rather
than just Assert'ing that the input is sane. Problem encountered while
investigating another issue (I saw a core dump in autoanalyze on a table
containing multiple empty tsquery values).
Back-patch to all branches with tsquery support.
In HEAD, also fix some bizarre (though not outright wrong) coding in

since Apple shipped a compiler that needed this switch, and there's
increasing interest in using other compilers that won't accept the switch
at all. Better to let anybody who still needs the switch inject it via
CPPFLAGS. Per gripe from Neil Conway.
While this hack arguably has some benefit in terms of making PL/pgsql's
line numbering match the programmer's expectations, it also makes
PL/pgsql inconsistent with the remaining PLs, making it difficult for
clients to reliably determine where the error actually is. On balance,
it seems better to be consistent.

from "clang". The VERR changes make an assignment unconditional, which is
probably easier to read/understand anyway, and one can hardly argue that
it's worth shaving cycles off the case of reporting another error when
one has already been detected. The INSIST change limits where that macro
can be used, but not in a way that creates a problem for any existing call.
