   Unfortunately, as I put in the original issue, given the sql `WHERE s_i_id = 
$1 AND s_w_id = $2` the planner calls the 
`TableProvider.supports_filter_pushdown()` with each part of the clause:
   
   ```
   ArrowTableProvider::supports_filter_pushdown() proj=stock.s_i_id = 
Int32(3604)
   ArrowTableProvider::supports_filter_pushdown() proj=stock.s_w_id = Int32(1)
   ```
   
   I suppose what I can do is just return `Exact` for everything, then the 
TableProvider would get the full predicate. Unfortunately that means it would 
also get `age > 21` which might be simple enough to deal with, but it would 
also have to evaluate all possible expressions `x / sqrt(pi) * UDF(y)` which 
starts looking more like something we'd want to have happening in a higher 
layer...
