an 'opclass owner' column in pg_opclass. Nothing is done with it at
present, but since there are plans to invent a CREATE OPERATOR CLASS
command soon, we'll probably want DROP OPERATOR CLASS too, which
suggests that a notion of ownership would be a good idea.
qualified operator names directly, for example CREATE OPERATOR myschema.+
( ... ). To qualify an operator name in an expression you need to write
OPERATOR(myschema.+) (thanks to Peter for suggesting an escape hatch).
I also took advantage of having to reformat pg_operator to fix something
that'd been bugging me for a while: mergejoinable operators should have
explicit links to the associated cross-data-type comparison operators,
rather than hardwiring an assumption that they are named < and >.
selected as the creation target namespace; to make that happen, you
must explicitly set search_path that way. This makes initdb a hair
more complex but seems like a good safety feature.
which covers some recent installation schemes.
Add Mandrake installation layout to directories to check for stylesheets.
Allow documentation build to proceed if stylesheets were not found, in case
the stylesheets might be found through the SGML catalog mechanism.
the libpgtcl "pg_execute" command. This was mentioned on
pgsql-interfaces on Mar 3. I am posting it here in the hope that someone
will check to see if it makes sense and is correct SGML-wise. I did run
it through jade, but this is my first try at this sort of thing.

entries, per pghackers discussion. This fixes aggregates to live in
namespaces, and also simplifies/speeds up lookup in parse_func.c.
Also, add a 'proimplicit' flag to pg_proc that controls whether a type
coercion function may be invoked implicitly, or only explicitly. The
current settings of these flags are more permissive than I would like,
but we will need to debate and refine the behavior; for now, I avoided
breaking regression tests as much as I could.
volatile), rather than the old cachable/noncachable distinction. This
allows indexscan optimizations in many places where we formerly didn't.
Also, add a pronamespace column to pg_proc (it doesn't do anything yet,
however).
A new pg_hba.conf column, USER
Allow specifiction of lists of users separated by commas
Allow group names specified by +
Allow include files containing lists of users specified by @
Allow lists of databases, and database files
Allow samegroup in database column to match group name matching dbname
Removal of secondary password files
Remove pg_passwd utility
Lots of code cleanup in user.c and hba.c
New data/global/pg_pwd format
New data/global/pg_group file
depend on this rather than the trigger argument strings to locate the
other relation to test. This makes RI triggers function properly in
the presence of schemas and temp tables. Along the way, fix bogus lack
of locking in RI triggers, handle quoting of names fully correctly,
compute required sizes of query buffers with some semblance of accuracy.
path. The default behavior if no per-user schemas are created is that
all users share a 'public' namespace, thus providing behavior backwards
compatible with 7.2 and earlier releases. Probably the semantics and
default setting will need to be fine-tuned, but this is a start.
in schemas other than the system namespace; however, there's no search
path yet, and not all operations work yet on tables outside the system
namespace.
the parsetree representation. As yet we don't *do* anything with schema
names, just drop 'em on the floor; but you can enter schema-compatible
command syntax, and there's even a primitive CREATE SCHEMA command.
No doc updates yet, except to note that you can now extract a field
from a function-returning-row's result with (foo(...)).fieldname.

Sorry Bruce, I was unclear. I have attached patch to Readme.tsearch
Also, It'd be worth to mention in Changes to point users of tsearch
about importang upgrade notices.
