Robert Haas 95ef7cd40d Make RecordTransactionCommit() respect wal_level.
Since the only purpose of WAL-loggin SharedInvalidationMessages is to support
Hot Standby operation, they needn't be included when wal_level < hot_standby.

Back-patch to 9.0.

Tom Lane e4155c8483 Fix pg_restore to complain if any arguments remain after parsing the switches
and input file name, per bug #5617 from Leo Shklovskii.  Rearrange the
corresponding code in pg_dump and pg_dumpall so that all three programs
handle this in a consistent, straightforward fashion.

Back-patch to 9.0, but no further.  Although this is certainly a bug, it's
possible that people have scripts that will be broken by the added error
check, so it seems better not to change the behavior in stable branches.

Tom Lane 00f76dbffa Get rid of a bunch of dubious error handling code in pgbench by just erroring
out immediately on any out-of-memory condition.  It's rather pointless to
imagine that pgbench will be able to continue usefully after a malloc
failure, and in any case there were a number of unchecked mallocs.

Tom Lane 568e709372 Extend psql's \e and \ef commands so that a line number can be specified,
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.

Tom Lane c04fd1b9db Remove the arbitrary (and undocumented) limit on the number of parameter=value
pairs that can be handled by xslt_process().

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

Tom Lane 33f43725fb Add three-parameter forms of array_to_string and string_to_array, to allow
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.

Tom Lane 46af71ff7e Fix incorrect logic in plpgsql for cleanup after evaluation of non-simple
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.

Tom Lane 2e35d4f35c Modify the handling of RAISE without parameters so that the error it throws
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.

Tom Lane e49ae8d3bc Recognize functional dependency on primary keys. This allows a table's
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

Robert Haas 31b6fc06d8 Fix inheritance count tracking in ALTER TABLE .. ADD CONSTRAINT.
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.
