How do I add to the cell that already exists.

eg: I have a row with a col named "website"

How do I add another website to this cell....like an array or something.

Before: "google(dot)com"
After: "google(dot)com, apple(dot)com"

Looking at the docs and sending data, **update** seems to overwrite the current content. Thank you.

Generally, the model is to read in the existing record, then add to it, then write the new version with `update` or `upsert`.

If you're trying to blindly add data to an existing column in the database and you don't have access to what's in it (throwing more data into a column that already has data), then you can do that by writing a simple `PostgreSQL function` that takes the new data as a parameter and updates the database by doing something like `update table set myCol = myCol || ' , ' || newData where x = y;`
