13 CGI::Session::Driver::postgresql - [[PostgreSQL]] driver for CGI::Session
17 use CGI::Session; $session = new CGI::Session("driver:PostgreSQL", undef, \{Handle=>$dbh\});
21 CGI::Session::PostgreSQL is a L<CGI::Session|CGI::Session> driver to store session data in a [[PostgreSQL]] table.
25 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:
27 CREATE TABLE sessions ( id CHAR(32) NOT NULL PRIMARY KEY, a\_session BYTEA NOT NULL );
29 and within your code use:
31 use CGI::Session; $session = new CGI::Session("driver:PostgreSQL", undef, \{Handle=>$dbh, [[ColumnType]]=>"binary"\});
33 Please note the I argument. [[PostgreSQL]]'s text type has problems when trying to hold a null character. (Known as C<"\\0"> in Perl, not to be confused with SQL I). If you know there is no chance of ever having a null character in the serialized data, you can leave off the I attribute. Using a I column type and C<< [[ColumnType]] => 'binary' >> is recommended when using L<Storable|CGI::Session::Serialize::storable> as the serializer or if there's any possibility that a null value will appear in any of the serialized data.
35 For more details see L<CGI::Session::Driver::DBI|CGI::Session::Driver::DBI>, parent class.
37 Also see L, which exercises different method for dealing with binary data.
