将数据帧存储在postgres中的一个单元格中

Question

I have a data.frame which contains the grouping logic of region for example:

data1 <- data.frame(
    Group = c(1, 2, 3), 
    Region = c("Southeast Med, Southeast Low, Southwest Low, Northeast Med", "Northeast High, East Med, Midwest Med High", "Midwest Low, California and HI, West High"),
    stringsAsFactors = F)

I want to store this information in one cell in postgres. How can I do it?

I tried converting it into a list , but that doesn't work. Other options I am considering is to serialize it. I tried creating it into a vector/string, but I lose the grouping information. I need to post it such that when I extract it, I can re-use it to group the data with the given information.

More details, or flow of thought can be sourced in this question: R: Creating a new column using another dataframe

Essentially, I am trying to store information from training data, and want to be able to replicate the grouping when new data comes in from the stored information. Happy to provide any more information that is needed, if I missed it.
