Deduplicate column names from postgres_query - #621
Merged
Merged
Conversation
Queries that return columns with same names currently cannot be run
through `postgres_query()`, because DuckDB requires table functions to
return distinct column names:
```sql
postgres=# SELECT 41, 42;
?column? | ?column?
----------+----------
41 | 42
(1 row)
```
This PR adds deduplication to the `postgres_query()` column names, the
example above is changed to: `?column?`, `?column?_1`.
