doesn't automatically inherit the privileges of roles it is a member of;
for such a role, membership in another role can be exploited only by doing
explicit SET ROLE.  The default inherit setting is TRUE, so by default
the behavior doesn't change, but creating a user with NOINHERIT gives closer
adherence to our current reading of SQL99.  Documentation still lacking,
and I think the information schema needs another look.

existing ones for object privileges.  Update the information_schema for
roles --- pg_has_role() makes this a whole lot easier, removing the need
for most of the explicit joins with pg_user.  The views should be a tad
faster now, too.  Stephen Frost and Tom Lane.

I'm still working on the has_role function and information_schema changes.

point(lseg, lseg), which does not exist, and the documentation seemed to
describe lseg_interpt, which we already document as an operator not a
function.  Also remove entry for box_intersect, which likewise is
preferentially used via the operator #.

optional arguments as text input functions, ie, typioparam OID and
atttypmod.  Make all the datatypes that use typmod enforce it the same
way in typreceive as they do in typinput.  This fixes a problem with
failure to enforce length restrictions during COPY FROM BINARY.

The Problem:  Occassionally a DBA needs to dump a database to a new
encoding.   In instances where the current encoding, (or lack of an
encoding, like SQL_ASCII) is poorly supported on the target  database
server, it can be useful to dump into a particular  encoding.  But,
currently the only way to set the encoding of  a pg_dump file is to
change  client_encoding in postgresql.conf and restart postmaster.
This is more  than a little awkward for production systems.

The specification of this function is as follows.

regexp_replace(source text, pattern text, replacement text, [flags
text])
returns text

Replace string that matches to regular expression in source text to
replacement text.

 - pattern is regular expression pattern.
 - replacement is replace string that can use '\1'-'\9', and '\&'.
    '\1'-'\9': back reference to the n'th subexpression.
    '\&'     : entire matched string.
 - flags can use the following values:
    g: global (replace all)
    i: ignore case
    When the flags is not specified, case sensitive, replace the first
    instance only.

This relies on the output of zic being platform independent, but that is
currently the case.
