Description
Originally filed here https://github.com/libsql/sqld/issues/287
The following SQL fails with this error using ibsql-experimental-python 0.0.25 and sqld 0.22.0.
File "/home/runner/work/django-libsql/django-libsql/django_repo/django/db/backends/sqlite3/base.py", line 227, in disable_constraint_checking
enabled = cursor.execute("PRAGMA foreign_keys").fetchone()[0]
ValueError: invalid column type
This code comes from Django's sqlite3 backend: https://github.com/django/django/blob/9c5e382b981608a26f2c55f1259d9e823fee5f15/django/db/backends/sqlite3/base.py#L238-L245

Research direction
Reproduce the failure with ibsql-experimental-python 0.0.25 and sqld 0.22.0 using the SQL shown in the issue. Read Django's sqlite3 backend at the linked base.py location to understand the expected PRAGMA foreign_keys result, then trace the libSQL path that handles this query. Done means the query works without the invalid column type error.
