Backpatch.

8.0), and add as suggestion to use log_min_error_statement for this
purpose.  I also fixed the code so the first EXECUTE has it's prepare,
rather than the last which is what was in the current code.  Also remove
"protocol" prefix for SQL EXECUTE output because it is not accurate.

Backpatch to 8.1.X.

	CREATE AGGREGATE aggname (input_type) (parameter_list)
along with the old syntax where the input type was named in the parameter
list.  This fits more naturally with the way that the aggregate is identified
in DROP AGGREGATE and other utility commands; furthermore it has a natural
extension to handle multiple-input aggregates, where the basetype-parameter
method would get ugly.  In fact, this commit fixes the grammar and all the
utility commands to support multiple-input aggregates; but DefineAggregate
rejects it because the executor isn't fixed yet.
I didn't do anything about treating agg(*) as a zero-input aggregate instead
of artificially making it a one-input aggregate, but that should be considered
in combination with supporting multi-input aggregates.

Put the text files in the right place during make dist, so there are no
extra manual steps required anymore.

that apply the necessary domain constraint checks immediately.  This fixes
cases where domain constraints went unchecked for statement parameters,
PL function local variables and results, etc.  We can also eliminate existing
special cases for domains in places that had gotten it right, eg COPY.

Also, allow domains over domains (base of a domain is another domain type).
This almost worked before, but was disallowed because the original patch
hadn't gotten it quite right.

functions are not strict, they will be called (passing a NULL first parameter)
during any attempt to input a NULL value of their datatype.  Currently, all
our input functions are strict and so this commit does not change any
behavior.  However, this will make it possible to build domain input functions
that centralize checking of domain constraints, thereby closing numerous holes
in our domain support, as per previous discussion.

While at it, I took the opportunity to introduce convenience functions
InputFunctionCall, OutputFunctionCall, etc to use in code that calls I/O
functions.  This eliminates a lot of grotty-looking casts, but the main
motivation is to make it easier to grep for these places if we ever need
to touch them again.

used within WAL files.  Historically this was the same as the data file
BLCKSZ, but there's no necessary connection, and it's possible that
performance gains might ensue from reducing XLOG_BLCKSZ.  In any case
distinguishing two symbols should improve code clarity.  This commit
does not actually change the page size, only provide the infrastructure
to make it possible to do so.  initdb forced because of addition of a
field to pg_control.

to fix regressions introduced in the recent patch adding additional
\connect options. This is based on work by Volkan YAZICI, although
this version of the patch doesn't bear much resemblance to Volkan's
version.

\connect takes 4 optional arguments: database name, user name, host
name, and port number. If any of those parameters are omitted or
specified as "-", the value of that parameter from the previous
connection is used instead; if there is no previous connection,
the libpq default is used. Note that this behavior makes it
impossible to reuse the libpq defaults without quitting psql and
restarting it; I don't really see the use case for needing to do
that.
