NAME
       Tangram::Driver::Pg - Orthogonal Object Persistence in PostgreSQL databases

SYNOPSIS
	  use Tangram;
	  use Tangram::Driver::Pg;

	  $schema = Tangram::Driver::Pg->schema( $hashref );

	  Tangram::Driver::Pg->deploy($schema, $dbh);

	  $storage = Tangram::Driver::Pg->connect( $schema,
	     $data_source, $username, $password );

	  $storage->disconnect();

	  Tangram::Driver::Pg->retreat($schema, $dbh);

DESCRIPTION
       This is the entry point in the Pg-specific object-relational persistence backend.

       This module performs the following:

METHODS
       This backend does not add any methods; for a description of available methods, see Tangram::Relational.

ERRATA
       Tangram::Type::Dump::Storable objects are first encoded with MIME::Base64, because Tangram does not currently have an easy mechanism for
       calling "DBI->bind_param()" at the appropriate time to flag the column as binary.

       Tangram::Type::Dump::Perl objects are stored as "BYTEA" columns, which as of DBD::Pg 1.31, also do not get correctly escaped by the DBD
       driver.	This also affects the (as-yet not fully functional) Tangram::Type::Dump::YAML back-end, which might put "" characters into a YAML
       document.

       It is recommended to use the "storable" type with Tangram::Type::Dump::Any for this reason.
