Just to keep people from accidentally setting a value that's dangerously

I think you're wrong there: The OP is querying a system table for tables of a
certain name, which I expect can contain multiple rows for tables of the same
name in different schema's.

I tried to create function to truncate table
1) when the user call the function just specify the tablename
2) the user can use the function owner privilege to execute the function.
But I got the errors as follows. Please help me to take a look.

Hi,
what about this:
SELECT p.rolname, m.rolname as member, g.rolname as grantor
FROM pg_authid p
INNER JOIN pg_auth_members am ON (p.oid = am.roleid)
INNER JOIN pg_authid m ON (am.member = m.oid)
INNER JOIN pg_authid g ON (am.grantor = g.oid)
You can use proper WHERE to filter results.
Regard
Thank you.

A sequential scan is what happens when the table is read sequentially.
One sequential scan can result in MANY tuples being read

In Windows PostgreSQL spawns numerous postgres.exe processes. When you
look at the actual command line you see the command that started the
process. For example: "c:/PostgreSQL/8.4/bin/postgres.exe" "--forkbackend"
"1372"
My questions
1. In the example above does 1372 represent a port?
2. If

This will list all roles in the cluster, whether they can login
