seddonm1 opened a new pull request #810:
URL: https://github.com/apache/arrow-datafusion/pull/810
# Which issue does this PR close?
Closes #809.
# Rationale for this change
Due to the way the field qualification works a query this does not work as
technically the field is qualified but the matching only works on complete
matches between the field qualifier `person` and the schema qualifier
`public.person`.
```sql
SELECT person.first_name FROM public.person
```
# What changes are included in this PR?
This PR adds:
- ability to partially match qualified fields against the schema.
- a rewrite step in the logical planner to rewrite the partial match to a
fully resolved qualifier so it can be used downstream.
# Are there any user-facing changes?
No, just more standard Postgres SQL will work.
