doc: Fix column_name parameter in ALTER MATERIALIZED VIEW

michaelpq · michaelpq · commit c0df15ac7e9e · 2024-05-23T13:03:16.000+09:00
Parameter column_name must be an existing column because ALTER MATERIALIZED VIEW cannot add new columns. The old description was likely copied from ALTER TABLE. Author: Erik Wienhold Discussion: https://postgr.es/m/6880ca53-7961-4eeb-86d5-6bd05fc2027e@ewie.name Backpatch-through: 12
