This allows the index to reference the pg_notify() subsection specifically,
rather than Notes section of the NOTIFY reference page more generally.

than during define_custom_variable().  This entails rejecting an ALTER
command if the target variable doesn't have a known (non-placeholder)
definition, unless the calling user is superuser.  When the variable *is*
known, we can correctly apply the rule that only superusers can issue ALTER
for SUSET parameters.  This allows define_custom_variable to apply ALTER's
values for SUSET parameters at module load time, secure in the knowledge
that only a superuser could have set the ALTER value.  This change fixes a
longstanding gotcha in the usage of SUSET-level custom parameters; which
is a good thing to fix now that plpgsql defines such a parameter.

At present, killing the startup process does not release any locks it holds,
so we must wait to stop the startup and walreceiver processes until all
read-only backends have exited.  Without this patch, the startup and
walreceiver processes never exit, so the server gets permanently stuck in
a half-shutdown state.

is changed to match the hard-wired default.  This avoids accumulating useless
catalog entries, and also provides a path for dropping the owning role without
using DROP OWNED BY.  Per yesterday's complaint from Jaime Casanova, the
need to use DROP OWNED BY for that is less than obvious, so providing this
alternative method might save some user frustration.

The endterm attribute is mainly useful when the toolchain does not support
automatic link target text generation for a particular situation.  In  the
past, this was required by the man page tools for all reference page links,
but that is no longer the case, and it now actually gets in the way of
proper automatic link text generation.  The only remaining use cases are
currently xrefs to refsects.

Also update tagging instructions, and add id tags to a few documentation

Also fix and uncomment an old example of creating a GIST index, and make
a couple of other minor editorial adjustments.

marked stable.

This operates in the same way as other CREATE OR REPLACE commands, ie,
it replaces everything but the ownership and ACL lists of an existing
entry, and requires the caller to have owner privileges for that entry.

While modifying an existing language has some use in development scenarios,
in typical usage all the "replaced" values come from pg_pltemplate so there
will be no actual change in the language definition.  The reason for adding
this is mainly to allow programs to ensure that a language exists without
triggering an error if it already does exist.

This commit just adds and documents the new option.  A followon patch
will use it to clean up some unpleasant cases in pg_dump and pg_regress.

(hope I got 'em all).  Per discussion, this release will be 9.0 not 8.5.

In addition, add support for a "payload" string to be passed along with
each notify event.

This implementation should be significantly more efficient than the old one,
and is also more compatible with Hot Standby usage.  There is not yet any
facility for HS slaves to receive notifications generated on the master,
although such a thing is possible in future.
