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?

Regards
Sud
