Hello

Sadly today we hit the 1600 columns limit of Postgresql 11.

How could we add more columns?

Note: Tables are OK. We truly have 2400 columns now. Each column represents a value in a matrix.

We have millions of rows so I would prefer not to transpose each row to (x, y, column_value) triplets because it will make all our code more difficult of what it is.

Any help, very appreciated.

Pablo
