I installed PostGreSQL 7.3 on Linux with uname -a as below:
Linux web1.jibenetworks.com 2.4.18-3 #1 Thu Apr 18 07:32:41 EDT 2002 i686 unknown 

make check passed all tests.

I also have Python 2.2.2 installed:

Python 2.2.2 (#1, Nov 18 2002, 14:41:56)
[GCC 2.96 20000731 (Red Hat Linux 7.3 2.96-110)] on linux2

The pgdb.py, pg.py and the pgmodule.so have been correctly installed 
into the python2.2 site-packages directory.

However, a basic query fails with the following error:

>>> cursor = db.cursor()
>>> cursor.execute('select * from provider;')
Traceback (most recent call last): File "<stdin>", line 1, in ? File "/usr/local/lib/python2.2/site-packages/pgdb.py",
line189, in execute   self.executemany(operation, (params,)) File "/usr/local/lib/python2.2/site-packages/pgdb.py",
line221, in executemany   desc = typ[1:2]+self.__cache.getdescr(typ[2]) File
"/usr/local/lib/python2.2/site-packages/pgdb.py",line 149, in getdescr   self.__source.execute(
 
_pg.error: ERROR:  Attribute "typprtlen" not found


The postmaster logs show the following:

bash-2.05a$ /usr/local/pgsql/bin/postmaster -D /usr/local/pgsql/data
LOG:  database system was shut down at 2002-12-03 16:30:33 PST
LOG:  checkpoint record is at 0/A5730C
LOG:  redo record is at 0/A5730C; undo record is at 0/0; shutdown TRUE
LOG:  next transaction id: 1023; next oid: 19422
LOG:  database system is ready
ERROR:  Attribute "typprtlen" not found

Is this a bug, or a misconfigured installation?

Pointers would be helpful.

Thanks,
