Tom Lane 893632be4e Clean up logging for extended-query-protocol operations, as per my recent 
proposal.  Parameter logging works even for binary-format parameters, and
logging overhead is avoided when disabled.

log_statement = all output for the src/test/examples/testlibpq3.c example
now looks like

LOG:  statement: execute <unnamed>: SELECT * FROM test1 WHERE t = $1
DETAIL:  parameters: $1 = 'joe''s place'
LOG:  statement: execute <unnamed>: SELECT * FROM test1 WHERE i = $1::int4
DETAIL:  parameters: $1 = '2'

and log_min_duration_statement = 0 results in

LOG:  duration: 2.431 ms  parse <unnamed>: SELECT * FROM test1 WHERE t = $1
LOG:  duration: 2.335 ms  bind <unnamed> to <unnamed>: SELECT * FROM test1 WHERE t = $1
DETAIL:  parameters: $1 = 'joe''s place'
LOG:  duration: 0.394 ms  execute <unnamed>: SELECT * FROM test1 WHERE t = $1
DETAIL:  parameters: $1 = 'joe''s place'
LOG:  duration: 1.251 ms  parse <unnamed>: SELECT * FROM test1 WHERE i = $1::int4
LOG:  duration: 0.566 ms  bind <unnamed> to <unnamed>: SELECT * FROM test1 WHERE i = $1::int4
DETAIL:  parameters: $1 = '2'
LOG:  duration: 0.173 ms  execute <unnamed>: SELECT * FROM test1 WHERE i = $1::int4
DETAIL:  parameters: $1 = '2'

(This example demonstrates the folly of ignoring parse/bind steps for duration
logging purposes, BTW.)

Along the way, create a less ad-hoc mechanism for determining which commands
are logged by log_statement = mod and log_statement = ddl.  The former coding
was actually missing quite a few things that look like ddl to me, and it
did not handle EXECUTE or extended query protocol correctly at all.

This commit does not do anything about the question of whether log_duration
should be removed or made less redundant with log_min_duration_statement.

PostgreSQL Database Management System
=====================================
  
This directory contains the source code distribution of the PostgreSQL
database management system.

PostgreSQL is an advanced object-relational database management system
that supports an extended subset of the SQL standard, including
transactions, foreign keys, subqueries, triggers, user-defined types
and functions.  This distribution also contains C language bindings.

PostgreSQL has many language interfaces including some of the more
common listed below:

C++ - http://thaiopensource.org/development/libpqxx/
JDBC - http://jdbc.postgresql.org
ODBC - http://odbc.postgresql.org
Perl - http://search.cpan.org/~dbdpg/
PHP - http://www.php.net
Python - http://www.initd.org/
Ruby - http://ruby.scripting.ca/postgres/

Other language binding are available from a variety of contributing
parties.

PostgreSQL also has a great number of procedural languages available,
a short but not complete list is below:

PL/pgSQL - included in PostgreSQL source distribution
PL/Perl - included in PostgreSQL source distribution
PL/PHP - http://projects.commandprompt.com/projects/public/plphp
PL/Python - included in PostgreSQL source distribution
PL/Java - http://gborg.postgresql.org/project/pljava/projdisplay.php
PL/Tcl - included in PostgreSQL source distribution

See the file INSTALL for instructions on how to build and install
PostgreSQL.  That file also lists supported operating systems and
hardware platforms and contains information regarding any other
software packages that are required to build or run the PostgreSQL
system.  Changes between all PostgreSQL releases are recorded in the
file HISTORY.  Copyright and license information can be found in the
file COPYRIGHT.  A comprehensive documentation set is included in this
distribution; it can be read as described in the installation
instructions.

The latest version of this software may be obtained at
http://www.postgresql.org/download/.  For more information look at our
web site located at http://www.postgresql.org/.
