Robert Haas ff499613d2 Several fixes for EXPLAIN (FORMAT YAML), plus one for EXPLAIN (FORMAT JSON). 
ExplainSeparatePlans() was busted for both JSON and YAML output - the present
code is a holdover from the original version of my machine-readable explain
patch, which didn't have the grouping_stack machinery.  Also, fix an odd
distribution of labor between ExplainBeginGroup() and ExplainYAMLLineStarting()
when marking lists with "- ", with each providing one character.  This broke
the output format for multi-query statements.  Also, fix ExplainDummyGroup()
for the YAML output format.

Along the way, make the YAML format use escape_yaml() in situations where the
JSON format uses escape_json().  Right now, it doesn't matter because all the
values are known not to need escaping, but it seems safer this way.  Finally,
I added some comments to better explain what the YAML output format is doing.

Greg Sabino Mullane reported the issues with multi-query statements.
Analysis and remaining cleanups by me.

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, many of which are listed here:

	http://www.postgresql.org/download

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/.
