You might define new types for temperature, length, whatever, with suitable
conversion, operation and creation functions. You’d be able to define how the
new types participate in indexes, support directly sorting on them, so you
package up this complexity and forget about it.

I would write a stable function converting everything to metric (or
imperial, depends on your preferences) and sort on the return of the

I'll put a table together with appropriate numeric types and see if the
sort will behave.

We have two tables, both have ~36 partitions.
This is my first query, which attempts to join the parent tables on the
columns that have been used to create multi-column indexes for all
partitions (multi-column indexes defined on session_id, detail_id in that
order):

Alright how is this different from metric or fraction?
I can sort of see fraction if you mean as 1/3, 1/20, etc.

Couldn't handle it with ORDER BY ASC, DESC args so I added a sort_column
and sorted based
on those values eg; 1,2,3,4,5,6 indicating the value I need t
