I get this exception with Django 1.0.2 + PostgrsSql 8.4 beta1 (compiled
from source):
{{{
File "/path/to/project/Django-1.0.2/django/db/backends/__init__.py",
line 56, in cursor
cursor = self._cursor(settings)
File
"/path/to/project/Django-1.0.2/django/db/backends/postgresql_psycopg2/base.py",
line 92, in _cursor
self.__class__._version = get_version(cursor)
File
"/path/to/project/Django-1.0.2/django/db/backends/postgresql/version.py",
line 16, in get_version
major, minor = VERSION_RE.search(version).groups()
AttributeError: 'NoneType' object has no attribute 'groups'
}}}
The problem is the RE used on django/db/backends/postgresql/version.py
(django-1.0.2):
{{{
VERSION_RE = re.compile(r'PostgreSQL (\d+)\.(\d+)\.')
}}}
When asked for the version, PostgreSql 8.4beta1 returns:
'''PostgreSQL 8.4beta1 on i686-pc-linux-gnu, compiled by GCC gcc (Ubuntu
4.3.2-1ubuntu12) 4.3.2, 32-bit'''
The RE used in Django 1.1 works OK:
{{{
VERSION_RE = re.compile(r'\S+ (\d+)\.(\d+)')
}}}
(the '\S+' is used to support EnterpriseDB, see ticket #8737).
I think django/db/backends/postgresql/operations.py (django-1.0.2) should
be modifyed too to make it compatible with EnterpriseDB.
Both files (version.py and operations.py) could be patched with
fix_re_django-1.0.2.diff.
I've also attached fix_re_django-1.1-dev.diff that changes operations.py
to support EnterpriseDB.
Other tickets (already closed) related to this are: #6433 #9931 #9953
I've tested that the patches are working against PostgreSQL 8.3 (Ubuntu
8.10) and PostgreSQL 8.4beta1 (from sources) but haven't check that those
changes works well with EnterpriseDB.
Thanks!
Horacio
