  1. comments on columns aren't displayed by \dd

    PostgreSQL Bugs List <pgsql-bugs@postgresql.org> — 2001-03-20T05:15:28Z

    Stephen van Egmond (svanegmond@home.com) reports a bug with a severity of 3
The lower the number the more severe it is.

Short Description
comments on columns aren't displayed by \dd

Long Description
Comments on columns appear to be broken.  CREATE COMMENT ON COLUMN inserts stuff into the backend pg_* tables correctly.  However \dd from the psql interactive monitor doesn't send a query to retrieve it (i.e. no join on pg_attribute).

I am working from the Debian package postgresql-client 7.0.3-2.

Sample Code
create table foo (a text);
cmment on column foo.a is 'hello!';
\dd foo.a

    Psql manual pages says:

              The command form \d+ is identical, but any comments
              associated  with  the  table  columns  are shown as
              well.

Thank you for the response, Bruce.  I was working from the HTML docs
for COMMENT ON  [1] where only \dd is mentioned.  \d+ doesn't occur in the 
\? psql help either.

The + options to psql are sort of COMMENT additions to the backslash
commands.

  5. libpqeasy cursor error after multiple calls

    Justin Clift <jclift@iprimus.com.au> — 2001-03-20T09:54:21Z

    Hi all,

I'm just wondering if this is an error on my part, or a bug.  I have the
same trouble with PG 7.1beta6 and PG7.1 snapshot (March 8th) on Solaris
8 INTEL, Solaris 8 SPARC and Linux Mandrake 7.2.

When using the libpqeasy library in a C function, I have the following
section of code :

  // Get the sequence number for the next directory entry (PostgreSQL
commands)
  doquery("BEGIN WORK");
  doquery("DECLARE c_getdirid BINARY CURSOR FOR SELECT
nextval('prescan_directories_idnum_seq'::text)");
  doquery("FETCH ALL IN c_getdirid");
  fetch(&enumdirstruc_p->presentdirid);
  doquery("CLOSE c_getdirid");
  doquery("COMMIT WORK");

This is called once per entry in a filesystem (this is a filesystem
scanning utility) but after about 1000 or so calls, it errors out and
won't work again.  I have to actually DROP the database and re-create it
again before the code will work again at all.  Just vacumming doesn't
help, nor does just shutting down the database and starting it again
(doing both and vacuum and restarting the database doesn't help either).

The error message is :

<list of files correctly inserted so far, then>
/archive/install/kde/kdeadmin-2.1/ksysctrl/.cvsignore
NOTICE: PerformPortalFetch: portal "c_getdirid" not found
NOTICE: PerformPortalClose: portal "c_getdirid" not found
Directory query failed, trying again...New directory idnum = -2147483648
(This is my error message from the program)
query error:
failed request: insert into prescan_files(filename, dirent, ownername,
owenerid, groupname, groupid, filesize, os, os_version, package_id)
values ('/archive/install/kde/kdeadmin-2.1/add-on/.cvsignore',
2147483648, 'jclift', 100, 'staff', 10, 21, 1, '8 INTEL', 16777216)
$

I can include the database schema and complete source code if needed,
but I'm just not sure where to start debugging... is it my app or is it
PostgreSQL?

Regards and best wishes,

Justin Clift

    I am kind of stumped.  Glad to see _someone_ is using libpgeasy.  :-)

I would be glad to run tests here if you can shoot over the code.

    Christopher Kings-Lynne <chriskl@familyhealth.com.au> — 2001-03-21T06:54:00Z

    I don't know but it may be that you're trying to insert a number larger than
maxint?

ie: 2147483648

???
