• I have verified this enhancement I'm about to request hasn't been suggested before.

Describe the enhancement you want to request

The docs here are unclear. If I use the syntax first described, I get a 'deprecated' warning. The second description below, which it states it the new syntax, does not include what should surround it (obviously these lines should not be on the top level).

// with on()
index('name')
  .on(table.column1.asc(), table.column2.nullsFirst(), ...) or .onOnly(table.column1.desc().nullsLast(), table.column2, ...)
  .concurrently()
  .where(sql``)
  .with({ fillfactor: '70' })
// with using()
index('name')
  .using('btree', table.column1.asc(), sql`lower(${table.column2})`, table.column1.op('text_ops'))
  .where(sql``) // sql expression
  .with({ fillfactor: '70' })

I'm going with the deprecated version for now as I don't know how to use the new format based on the current docs. If anyone knows how this should be done I'd greatly appreciate the help.
