Wiki / Functions

Creates or updates column-level statistics. Ordinarily, these statistics are collected automatically or updated as a part of VACUUM or ANALYZE, so it's not necessary to call this function. However, it is useful after a restore to enable the optimizer to choose better plans if ANALYZE has not been run yet.

English manual coverage begins with PostgreSQL 7.1. Source history and runtime observations have their own recorded version boundaries.
