NAME

6       CGI::Session::Driver::postgresql - PostgreSQL driver for CGI::Session
7

SYNOPSIS

9           use CGI::Session;
10           $session = CGI::Session->new("driver:PostgreSQL", undef, {Handle=>$dbh});
11

DESCRIPTION

13       CGI::Session::PostgreSQL is a CGI::Session driver to store session data
14       in a PostgreSQL table.
15

STORAGE

17       Before you can use any DBI-based session drivers you need to make sure
18       compatible database table is created for CGI::Session to work with.
19       Following command will produce minimal requirements in most SQL
20       databases:
21
22           CREATE TABLE sessions (
23               id CHAR(32) NOT NULL PRIMARY KEY,
24               a_session BYTEA NOT NULL
25           );
26
27       and within your code use:
28
29           use CGI::Session;
30           $session = CGI::Session->new("driver:PostgreSQL", undef, {Handle=>$dbh, ColumnType=>"binary"});
31
32       Please note the ColumnType argument. PostgreSQL's text type has
33       problems when trying to hold a null character. (Known as "\0" in Perl,
34       not to be confused with SQL NULL). If you know there is no chance of
35       ever having a null character in the serialized data, you can leave off
36       the ColumnType attribute. Using a BYTEA column type and "ColumnType =>
37       'binary'" is recommended when using Storable as the serializer or if
38       there's any possibility that a null value will appear in any of the
39       serialized data.
40
41       To use different column names, change the 'create table' statement, and
42       then simply do this:
43
44           $s = CGI::Session->new('driver:pg', undef,
45           {
46               TableName=>'session',
47               IdColName=>'my_id',
48               DataColName=>'my_data',
49               DataSource=>'dbi:pg:dbname=project',
50           });
51
52       or
53
54           $s = CGI::Session->new('driver:pg', undef,
55           {
56               TableName=>'session',
57               IdColName=>'my_id',
58               DataColName=>'my_data',
59               Handle=>$dbh,
60           });

65       with binary data.
