NAME

       CGI::Session::Serialize::yaml - serializer for CGI::Session

DESCRIPTION

       This library can be used by CGI::Session to serialize session data. It uses "YAML", or the faster C implementation, "YAML::Syck" if it is
       available. YAML serializers exist not just for Perl but also other dynamic languages, such as PHP, Python, and Ruby, so storing session
       data in this format makes it easy to share session data across different languages.

       YAML is made to be friendly for humans to parse as well as other computer languages. It creates a format that is easier to read than the
       default serializer.

METHODS

       freeze($class, \%hash)
	   Receives two arguments. First is the class name, the second is the data to be serialized. Should return serialized string on success,
	   undef on failure. Error message should be set using "set_error()|CGI::Session::ErrorHandler/"set_error()""

       thaw($class, $string)
	   Received two arguments. First is the class name, second is the "YAML" data string. Should return thawed data structure on success,
	   undef on failure. Error message should be set using "set_error()|CGI::Session::ErrorHandler/"set_error()""

NAME

       CGI::Session::Driver::postgresql - PostgreSQL driver for CGI::Session

SYNOPSIS

	   use CGI::Session;
	   $session = new CGI::Session("driver:PostgreSQL", undef, {Handle=>$dbh});

DESCRIPTION

       CGI::Session::PostgreSQL is a CGI::Session driver to store session data in a PostgreSQL table.

STORAGE

       Before you can use any DBI-based session drivers you need to make sure compatible database table is created for CGI::Session to work with.
       Following command will produce minimal requirements in most SQL databases:

	   CREATE TABLE sessions (
	       id CHAR(32) NOT NULL PRIMARY KEY,
	       a_session BYTEA NOT NULL
	   );

       and within your code use:

	   use CGI::Session;
	   $session = new CGI::Session("driver:PostgreSQL", undef, {Handle=>$dbh, ColumnType=>"binary"});

       Please note the ColumnType argument. PostgreSQL's text type has problems when trying to hold a null character. (Known as "" in Perl, not
       to be confused with SQL NULL). If you know there is no chance of ever having a null character in the serialized data, you can leave off the
       ColumnType attribute. Using a BYTEA column type and "ColumnType => 'binary'" is recommended when using Storable as the serializer or if
       there's any possibility that a null value will appear in any of the serialized data.

       To use different column names, change the 'create table' statement, and then simply do this:

	   $s = new CGI::Session('driver:pg', undef,
	   {
	       TableName=>'session',
	       IdColName=>'my_id',
	       DataColName=>'my_data',
	       DataSource=>'dbi:pg:dbname=project',
	   });

       or

	   $s = new CGI::Session('driver:pg', undef,
	   {
	       TableName=>'session',
	       IdColName=>'my_id',
	       DataColName=>'my_data',
	       Handle=>$dbh,
	   });

       For more details see CGI::Session::Driver::DBI, parent class.

       Also see sqlite driver, which exercises different method for dealing with binary data.
