Tangram::Driver::Pg(3pm) User Contributed Perl Documentation Tangram::Driver::Pg(3pm) 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. perl v5.8.8 2006-03-29 Tangram::Driver::Pg(3pm)
