# Alzabo::Driver::PostgreSQL(3pm)

PostgreSQL specific Alzabo driver subclass

## NAME

Alzabo::Driver::PostgreSQL - PostgreSQL specific Alzabo driver subclass

## SYNOPSIS

```
  use Alzabo::Driver::PostgreSQL;
```

## DESCRIPTION

This provides some PostgreSQL specific implementations for the virtual methods in Alzabo::Driver.

## METHODS

### connect, create\_database, drop\_database

Besides the parameters listed in the Alzabo::Driver docs, the following parameters are accepted:

- •

  options

- •

  tty

### schemas

This method accepts the same parameters as the `"connect()"` method.

### get\_last\_id

Returns the last id created for a sequenced column.

### identifier\_length

Returns the maximum identifier length allowed by the database.  This is really a guess based on the server version, since the actual value is set when the server is compiled.

## BUGS

In testing, I found that there were some problems using Postgres in a situation where you start the app, connect to the database, get some data, fork, reconnect, and and then get more data.  I suspect that this has more to do with the DBD::Pg driver and/or Postgres itself than Alzabo.  I don't believe this would be a problem with an app which forks before ever connecting to the database (such as mod\_perl).
