On: New In Postgres 12: Generated Columns

[tirumaraiselvan]

Why do they call it Generated Columns and not Computed Columns like most other databases already do?

[PeterisP → tirumaraiselvan]

IMHO "computed columns" generally implies columns that are computed on-demand when read, as opposed to this case when they're computed when the row is altered and persisted in the table.

[t0astbread → tirumaraiselvan]

I guess every column is "computed" if you think about it? It's nitpicky and I don't know the official reason though.

[fowl2 → tirumaraiselvan]

Possibly because they're closer to "persisted calculated columns".
