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.
