When https://code.djangoproject.com/ticket/18332 lands (No generic way
to get database backend version) this will be trivial but I need a
solution for this now: How can I find out which version of postgres is
in use?
I need it thanks to JSONField. 9.6 has support for it but older
postgresqls don't, and I'd like to then use a third-party
json-in-TextField solution instead.
A model with a django.contrib.postgres.fields.JSONField cannot be
migrated on posgresqls older than 9.4. (We run 9.3 and I need this
project to run on >=9.3) You get 'django.db.utils.ProgrammingError:
type "jsonb" does not exist'. At that point it's a little late
swapping out the import.
