I believe that patch also intended to remove contrib/ltree/patch.72

Please use this patch instead of my previously submitted one.

It is just remerged against HEAD for new alter_table.out stuff.

Another reason this patch is useful for _interactive_ users: imagine a
view based on a many way join.  Imagine creating a complicated insert
rule that inserts into all the joined tables and when you insert you get
a check failure, but you need to know which actual table the constraint
was on that failed!

documentation for SET, SHOW, and COPY.

ERROR:  ExecInsert: rejected due to CHECK constraint insert_con

To be like this:

ERROR:  ExecInsert: rejected due to CHECK constraint "insert_con" on
"insert_tbl"

Updated regression tests to match.

I got sick of seeing 'rejected due to CHECK constraint "$1" in my log and
not being able to find the bug in our website code...

functionality of the command is basically identical to that of
BEGIN; it just accepts a few extra options (only one of which
PostgreSQL currently implements), and is standards-compliant.
The patch includes a simple regression test and documentation.

[ Regression tests removed, per Peter.]

Neil Conway

there was a race condition between the "alter_table" and "rules"
regression tests. Depending on scheduling, sometimes an ALTER
TABLE command would operate on a relation created by the "rules"
tests, leading to unexpected results.

in the relcache.  It's rather silly that we have reference count leak
checks in bufmgr and in catcache, but not in relcache which will normally
have many fewer entries.  Chris K-L would have caught at least one bug
in his recent DROP patch if he'd had this.

relation being modified.  In most paths of control we'd already have
such a lock, but if we were dropping the default due to a cascaded
delete of some function it depended on, maybe not.

code review by Tom Lane.  Remaining issues: functions that take or
return tuple types are likely to break if one drops (or adds!)
a column in the table defining the type.  Need to think about what
to do here.

Along the way: some code review for recent COPY changes; mark system
columns attnotnull = true where appropriate, per discussion a month ago.

   whose first non-space character is '('.
2) Handle Insert .. () VALUES ().

attstattarget to indicate 'use the default'.  The default is now a GUC
variable default_statistics_target, and so may be changed on the fly.  Along
the way we gain the ability to have pg_dump dump the per-column statistics
target when it's not the default.  Patch by Neil Conway, with some kibitzing
from Tom Lane.

this only works against 7.3 or later databases; the pushups required
to do it without regprocedure/regtype/etc seem more trouble than they're
worth, considering that existing users aren't expecting pg_dump support
for this.

< 	o ALTER TABLE ADD COLUMN column SET DEFAULT should fill existing

< 	o ALTER TABLE ALTER COLUMN column SET DEFAULT should fill existing
> 	o ALTER TABLE ADD COLUMN column SET DEFAULT should fill existing

All of the internal tags are of the latter.

The other thing I noticed is that most of the quick examples in the file
use a para and synopsis.  Is there a reason we're not using <example/> ?
