NAME

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

SYNOPSIS

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

       Please note the ColumnType argument. PostgreSQL's text type has problems when trying to
       hold a null character. (Known as "\0" 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 = CGI::Session->new('driver:pg', undef,
           {
               TableName=>'session',
               IdColName=>'my_id',
               DataColName=>'my_data',
               DataSource=>'dbi:pg:dbname=project',
           });

       or

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

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

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