I use Django and just dropped and re-created database in order to flush table data. Now when I'm trying to do any db-related task, I get:
./manage.py sql portfolio
Traceback (most recent call last):

psycopg2.InternalError: BŁĄD: current transaction is aborted, commands ignored until end of transaction block
As you can see it's just code generation, so there should not be any problem with transaction. What's going on? :-(
That error means that something happened to your Postgres process that caused it to fail in the middle of a transaction but the transaction was never committed or rolled back, so it's stuck.
Basically you need to either issue a rollback command (this can be done from the Django shell, oftentimes), or kill the postgres process.
Note that (depending on your server config) Postgres processes keep running even if Django is not, so you're getting the same error every time because it's probably still stuck in the same process.
If you've done that and it's still doing this every time then it means you're triggering the error in your actual code somewhere and need to go digging.
Check postgres log file, to see the actual query responsible for database error. and try to find which portion of django makes this query.
Also check out https://github.com/django-debug-toolbar/django-debug-toolbar/issues/351 . It says django-debug-toolbar might be responsible for this error. Try disabling it.
