Hi All,
It's postgres database version 15.4. We have a table which is daily and is approx. ~2TB in size having a total ~90 partitions. We have a requirement to drop columns and add new columns to this table.

I Want to understand, If this can be done online? what is the fastest way to drop/add columns from such a big table and what will be the consequence of this in regards to vacuum, post this activity? Or if any other issues we may face post this?
