Hello,

I run a query transforming huge tables to a json document based on a period.
It works great for a modest period (little dataset). 
However, when increasing the period (huge dataset) I get this error:
SQL ERROR[54000]
ERROR: array size exceeds the maximum allowed (1073741823)


​Maximum Field Size: 1 GB​

It means a json cannot exceed 1GB in postgresql, right ?

​Yes​
 
Then I must build it with an external tool ?

​​You have to do something different.  Using multiple columns and/or multiple rows might we workable.
