Listening to realtime events on varchar[] column always returns ['archa'] and not the actual array content

Bug report

Describe the bug

Listening to realtime events on a column with varchar[] type always returns ['archa'] no matter what you enter as the value within the payload. It also seems like other array types are not returning the correct values either.

Mentioned supabase/supabase-dart#44

To Reproduce

Steps to reproduce the behavior, please provide code snippets or a repository:

1. Create a table with column of varchar[] type
2. Start listening to realtime events of the table
3. Make modification to the table so that realtime event fires
4. Receive ['archa'] as the value for varchar[] type column

Expected behavior

Should receive the actual array content as payload
