Apache::Session::Store::Postgres - Store persistent data in a Postgres database


 use Apache::Session::Store::Postgres;
 my $store = new Apache::Session::Store::Postgres;


Apache::Session::Store::Postgres fulfills the storage interface of Apache::Session. Session data is stored in a Postgres database.


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.


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:


 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
