Arel node for an array element (suffix operator)

[printercu]

Hi!

Is there any node for suffix operators to access array elements (postgresql's integer[] type) like this:

column = Table.arel_table[:column]
low = here_magic_happens(column, '[1]')
Table.where(low.eq nil).or(Table.where(low.gt 5))
# should result in this where clause:
# "table"."column"[1] IS NULL OR "table"."column"[1] > 5

Thank you!

Nope, there isn't. But if you send a pull request that implements it, we could talk about merging it in! 😀

@tenderlove can you please give some advises on this feature. Maybe there is already something very similar in the gem, or some class to inherit, module to include, etc.

Thank you!
