NAME
Apache::Session::Store::Postgres - Store persistent data in a Postgres database
SYNOPSIS
use Apache::Session::Store::Postgres;
my $store = new Apache::Session::Store::Postgres;
$store->insert($ref);
$store->update($ref);
$store->materialize($ref);
$store->remove($ref);DESCRIPTION
Apache::Session::Store::Postgres fulfills the storage interface of Apache::Session. Session data is stored in a Postgres database.
SCHEMA
To use this module, you will need at least these columns in a table called 'sessions', or another name if you supply the TableName parameter.
id char(32) # or however long your session IDs are.
a_session text # This has an ~8 KB limit :(To create this schema, you can execute this command using the psql program:
CREATE TABLE sessions (
id char(32) not null primary key,
a_session text
);If you use some other command, ensure that there is a unique index on the table's id column.
CONFIGURATION
The module must know what datasource, username, and password to use when connecting to the database. These values can be set using the options hash (see Apache::Session documentation). The options are:
- DataSource
- UserName
- Password
- Handle
- TableName
Example:
tie %hash, 'Apache::Session::Postgres', $id, {
DataSource => 'dbi:Pg:dbname=database',
UserName => 'database_user',
Password => 'K00l'
};Instead, you may pass in an already-opened DBI handle to your database.
tie %hash, 'Apache::Session::Postgres', $id, {
Handle => $dbh
};AUTHOR
