Hi Everybody,

My environment:
Windows 2008 32 bit
Postgres 9.0

I have two unrelated questions:

1.	Permissions:
When I create a login role with superuser privileges in pgAdminIII I have the option of indicating that the superuser will also have the permission to: "can modify catalog directly", when I look at the sql that is generated by that gui, I do not see a corresponding sql permission, I see:
"CREATE ROLE kasia LOGIN ENCRYPTED PASSWORD 'md5ff0508b7bb33909c096d1b447a17d09b'
  SUPERUSER VALID UNTIL 'infinity';"
A.	What does "can modify catalog directly" actually do? I looked it up and I found : "This option determines whether the role can modify system catalog directly or not." But that really does not tell me much.
B.	Why is there no sql level equivalent? When I revoke the "can modify catalog directly" permission I get the following sql:  UPDATE pg_authid SET rolcatupdate=false WHERE OID=17331::oid; 


2.	Postgres client dlls on windows
I am trying to identify the dlls that are considered postgres client libraries

In 8.3.8 and 8.4.1 they were:
Libpq.dll, comerr32.dll, gssapi32.dll, k5sprt32.dll, libeay32.dll, libiconv2.dll, libintl3.dll, ssleay32.dll

In 9.0 they seem to be:
Libpq.dll, ssleay32.dll, libeay32.dll, libintl-8.dll - IS THIS CORRECT?
-	Looking at the libpq dependencies the rest seem to be windows os dll


Thank you,
Sincerely,
Kasia

Yeah, we kinda suck at documenting things :)

It refers to the rolcatupdate column in the pg_authid system table.
Which is a permission to update the system catalogs (system tables).

> B.	Why is there no sql level equivalent? When I revoke the "can modify catalog directly" permission I get the following sql:  UPDATE pg_authid SET rolcatupdate=false WHERE OID=17331::oid; 

You create a superuser, which already has this capacity. So we don't
need to add something else. Of course, if you uncheck it, we'll have to
update the system table to set it to false.

Hi Guillaume,
Thanks for your reply I did a bit more testing with the superuser priv issue, and now I came to the conclusion that pgAdminIII may be doing something silly.

I created a user: bob

In pgAdminIII I checked off the box for: can inherit from parent role, can create db object, superuser
Got the following sql: 
CREATE ROLE bob LOGIN
  ENCRYPTED PASSWORD 'md51e9484aace238e7cb2609130fd87646e'
  SUPERUSER INHERIT CREATEDB NOCREATEROLE;
UPDATE pg_authid SET rolcapupdate=false WHERE rolname='bob';

Than I created bobb
In pgAdminIII I checked off the box for: can inherit from parent role, can create db object, superuser, Can modify catalog directly
Got the following sql: 
CREATE ROLE bobb LOGIN
  ENCRYPTED PASSWORD 'md51e9484aace238e7cb2609130fd87646e'
  SUPERUSER INHERIT CREATEDB NOCREATEROLE;


Conclusion:
Sql level superuser = pgAdminIII superuser + can modify catalog directly

This is misleading, I would call it a pgAdminIII bug but who knows maybe it is a feature...

Sincerely,
Kasia

Sure, that happens more than I would like.

I would not call it a feature. I find this misleading too. I'm too tired
right now to work on a fix, but it'll be easy and quick to do.

I have a few things to commit tomorrow. I'll try to work on this at the
same time.

Thanks for your inputs.

OK, was really simple to fix. See the patch attached.

Any comments on this patch? I'm ready to commit it on 1.12 and master,
if no-one objects.

Thanks.
