NAME

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

SYNOPSIS

9           use CGI::Session;
10           $session = new CGI::Session("driver:PostgreSQL", undef, {Handle=>$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 data‐
20       bases:
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           $session = new CGI::Session("driver:PostgreSQL", undef, {Handle=>$dbh, ColumnType=>"binary"});
31
32       Please note the ColumnType argument. PostgreSQL's text type has prob‐
33       lems when trying to hold a null character. (Known as "\0" in Perl, not
34       to be confused with SQL NULL). If you know there is no chance of ever
35       having a null character in the serialized data, you can leave off the
36       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.

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