Purpose and background context

Why these changes are being introduced:

We were encountering some errors after SQLAlchemy automatically updated to 2.0.45 that mentioned "pg_catalog" and "pg_collation". We use duckdb_engine, a SQLAlchemy engine, to interact with our DuckDB connection. It looks as though SQLAlchemy 2.0.45 -- for reasons unknown at this time -- break that engine, at least the table reflection which we use on TIMDEXDataset inititialization.

How this addresses that need:

  • Pins SQLAlchemy to 2.0.44 until we learn more or a new version is released.

Side effects of this change:

  • SQLAlchemy will be pinned until touched again.
