Bug reference:      4316
Logged by:          blueos
Email address:      blueos@free.fr
PostgreSQL version: 8.3.3
Operating system:   Linux
Description:        13 seconds to complete SELECT * FROM
pg_catalog.pg_attribute
Details:

On a server with 5 databases (a schema containing 59 tables and 58
sequences),
a SELECT * FROM  pg_catalog.pg_attribute takes 13s to complete.

It returns 4063 lines.

The server is a high end Intel dual core with 4Go of memory, the database is
only about 1MB of data! on this machine, a typical query returns in less
than 60ms.

A strange performance issue.

Regards,
Guillaume
