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 different namespaces.  Also, cleanup work on relation namespace
support: drop, alter, rename commands work for tables in non-default
namespaces.

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.

Also, fix debug logging of parse/plan trees so that the messages actually

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
