3f936aacc0 Add a "LIKE = typename" clause to CREATE TYPE for base types. This allows 
the basic representational details (typlen, typalign, typbyval, typstorage)
to be copied from an existing type rather than listed explicitly in the
CREATE TYPE command.  The immediate reason for this is to provide a simple
solution for add-on modules that want to define types represented as int8,
float4, or float8: as of 8.4 the appropriate PASSEDBYVALUE setting is
platform-specific and so it's hard for a SQL script to know what to do.

This patch fixes the contrib/isn breakage reported by Rushabh Lathia.

1304f297a4 Remove PGINTERVALSTYLE from the set of special environment variables for 
libpq.  As noted by Peter, adding this variable created a risk of unexpected
connection failures when talking to older server versions, and since it
doesn't do anything you can't do with PGOPTIONS, it doesn't seem really
necessary.  Removing it does occasion a few extra lines in pg_regress.c,
but saving a getenv() call per libpq connection attempt is perhaps worth
that anyway.

18004101ac Modify UPDATE/DELETE WHERE CURRENT OF to use the FOR UPDATE infrastructure to 
locate the target row, if the cursor was declared with FOR UPDATE or FOR
SHARE.  This approach is more flexible and reliable than digging through the
plan tree; for instance it can cope with join cursors.  But we still provide
the old code for use with non-FOR-UPDATE cursors.  Per gripe from Robert Haas.

32cc9e5533 Reduce contrib/intagg to a thin wrapper around the new core functions 
array_agg() and unnest().  We could drop it entirely in the future,
but let's keep it for a release or two as a compatibility assist.

d129255077 Set SQL man pages to be section 7 by default, and only transform them to 
another section if required by the platform (instead of the old way of
building them in section "l" and always transforming them to the
platform-specific section).

This speeds up the installation on common platforms, and it avoids some
funny business with the man page tools and build process.

c889ebce0a Implement the basic form of UNNEST, ie unnest(anyarray) returns setof 
anyelement.  This lacks the WITH ORDINALITY option, as well as the multiple
input arrays option added in the most recent SQL specs.  But it's still a
pretty useful subset of the spec's functionality, and it is enough to
allow obsoleting contrib/intagg.

2b2fb7d85d Support for man page links, if a man page has more than one refname. 
We don't actually use this anywhere, but it might come in handy for dealing
with SELECT/WITH/TABLE.

It works with both the old and the new man page target (for some value of
"works").

f98f6ee064 array_length() function, and for SQL compatibility also cardinality() 
function as a special case.

This version still has the suspicious behavior of returning null for an
empty array (rather than zero), but this may need a wholesale revision of
empty array behavior, currently under discussion.

a4917bef0e Add support for input and output of interval values formatted per ISO 8601; 
specifically, we can input either the "format with designators" or the
"alternative format", and we can output the former when IntervalStyle is set
to iso_8601.
