11285	postgresql server version as a static variable	findepi	nobody	"In {{{django.db.backends.postgresql.base}}} and {{{django.db.backends.postgresql_psycopg2.base}}} modules there is a code:

{{{
#!python
cursor = self.connection.cursor()
if set_tz:
    cursor.execute(""SET TIME ZONE %s"", [settings_dict['TIME_ZONE']])
    if not hasattr(self, '_version'):
        self.__class__._version = get_version(cursor)
    if self._version[0:2] < (8, 0):
}}}

It means that the server version is checked only at the first connection. I understand that django does not support and maybe will never support multiple different db connections from one process, but this may brake things even in case of database failover
E.g. at one network address there may be postgresql servers of different version available.
