| 613755043 | MDU6SXNzdWU2MTM3NTUwNDM= | 110 | Support decimal.Decimal type | 134771 | closed | 0 | 6 | 2020-05-07T03:57:19Z | 2020-05-11T01:58:20Z | 2020-05-11T01:50:11Z | NONE | Decimal types in Postgres cause a failure in db.py data type selection --- I have a Django app using a MoneyField, which uses a `numeric(14,0)` data type in Postgres (https://www.postgresql.org/docs/9.3/datatype-numeric.html). When attempting to export that table I get the following error: ```bash $ db-to-sqlite --table isaweb_proposal "postgres://connection" test.db .... column_type=COLUMN_TYPE_MAPPING[column_type], KeyError: <class 'decimal.Decimal'> ``` Looking at `sql_utils.db.py` at 292-ish it's clear that there is no matching type for what I assume SQLAlchemy interprets as Python decimal.Decimal. From the [SQLite docs](https://www.sqlite.org/datatype3.html#affinity_name_examples) it looks like DECIMAL in other DBs are considered numeric. I'm not quite sure if it's as simple as adding a data type to that list or if there are repercussions beyond it.
