The SQL Profiler Plugin allows you to profile a server's workload. You must install the plugin on each server on which you wish to use SQL Profiler (since it is a plugin to the database server, you must install a copy of the plugin for each Postgres instance you wish to profile on each host you wish to profile). For example, if you have a host running PostgreSQL 8.4 and PostgreSQL 9.0, you must install two versions of the plugin, one for each server.SQL Profiler for Postgres Enterprise Manager™ is officially supported only on the EnterpriseDB distributions of PostgreSQL version 8.4 (and above) and Postgres Plus Advanced Server version 9.0 (and above). The plugin is distributed via StackBuilder, or is available from the EnterpriseDB website at:The plugin is also distributed and installed with the server component of the Postgres Plus Advanced Server 9.0 (and above) installer.The SQL Profiler plugin may be installed on servers with or without a PEM agent, however traces can only be run in ad-hoc mode on unmanaged servers, and may only be scheduled on managed servers.Follow the installation steps listed below to install the plugin for PostgreSQL before continuing to the Configuration section. If you are using Postgres Plus Advanced Server 9.0 or above, skip ahead to the Configuration section.
