Daniel Gustafsson 664d757531 Refactor background psql TAP functions 
This breaks out the background and interactive psql functionality into a
new class, PostgreSQL::Test::BackgroundPsql.  Sessions are still initiated
via PostgreSQL::Test::Cluster, but once started they can be manipulated by
the new helper functions which intend to make querying easier.  A sample
session for a command which can be expected to finish at a later time can
be seen below.

  my $session = $node->background_psql('postgres');
  $bsession->query_until(qr/start/, q(
    \echo start
	CREATE INDEX CONCURRENTLY idx ON t(a);
  ));
  $bsession->quit;

Patch by Andres Freund with some additional hacking 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:

	https://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.  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
https://www.postgresql.org/download/.  For more information look at our
web site located at https://www.postgresql.org/.
