Expand description

CREATE INDEX over a system column, which PostgreSQL resolves like any attribute and then refuses to index.

Functions§

reject_system_column_index
Fail a CREATE INDEX that reads a system column as DefineIndex fails it: once the access method and each attribute are resolved and a unique index is matched against the partition key. columns are the table’s columns and partition its partition key; a statement that reads no system column passes.
